fix(main/fish): do not patch rust-lang/libc cargo crate

[robertkirkman]

• Fixes [Bug]: fish shell file globbing not working #24741

• Cherry-pick fish-shell/fish-shell@bbf678e to replace libc-src-unix-linux_like-android-mod.rs.diff (since libandroid-spawn does not currently work with fish)

• libc-src-unix-linux_like-android.diff is causing [Bug]: fish shell file globbing not working #24741 because of the problems explained by maurer in android: use proper types for dirent.d_ino, dirent.d_off, stat.st_mode and stat64.st_mode rust-lang/libc#4216 (comment)

• I have rewritten libc-src-unix-linux_like-android.diff in my own alternative way of solving the errors

  • My personal belief is that these errors should be solved by patching fish, not by patching the libc cargo crate.
  • The reason I believe that is because fish is using the type libc::ino_t to represent a value for storing the d_ino member of a dirent struct, which cannot work on 32-bit Android because 32-bit Android's d_ino is not an ino_t. It is a uint64_t.
  • Therefore, the logical conclusion is that any successful port of fish to 32-bit Android must explicitly store the value of a dirent d_ino as a u64 anywhere it appears in Rust code.
  • The same concept applies to st_mode - st_mode of stat on 32-bit Android is not a mode_t. It is an unsigned int, and on Android, unsigned int is a 32-bit integer. Therefore, any successful port of fish to 32-bit Android must explicitly store the value of a stat st_mode as u32.
  • In C, S_IFMT is a pure typeless literal preprocessor definition, which is (octal) 00170000 in Android, preprocessor definitions do not really exist in Rust so there is unfortunately no correct alternative to a hardcoded integer literal for this on 32-bit Android

• I previously read android: use proper types for dirent.d_ino, dirent.d_off, stat.st_mode and stat64.st_mode rust-lang/libc#4216 in January 2025, however, I unfortunately did not have the experience necessary at the time to fully understand how to solve this specific problem, so at the time, I did not change the version written by thunder-coding because I did not know how to make a better way to bypass the errors

  • However, in April 2025, I ported Steel Bank Common Lisp to 64-bit Android-x86. In the process of doing that, I became more experienced with Android's stat.h and dirent.h files, and I have been able to use that experience to successfully create what appears to be a correct solution to [Bug]: fish shell file globbing not working #24741

The original errors, repeated here for convenient reference by others:

This is confirmed to also solve the problem on the device of the issue reporter, so I am merging it now.
