Add --remove-needed-version

[chitao1234]

This pr adds a new switch --remove-needed-version, to removing symbol versioning used by libraries like glibc. This switch should fix the use case of issue #284, #252.

I have included a regression test and updated the man page.

i hope this gets added because i regularly run into this use case when dealing with either legacy software or when copying software to unsusual platforms like the steamdeck.

my current issue is trying to copy waypipe to steamdeck

Thank you for the great tool

It works fine with gnu toolchain, but when I compile with clang I get

patchelf: /home/maxirmx/Projects/tebako/deps/src/_patchelf/src/patchelf.cc:946: void ElfFile<Elf64_Ehdr, Elf64_Phdr, Elf64_Shdr, unsigned long, unsigned long, Elf64_Dyn, Elf64_Sym, unsigned short, Elf64_Verdef, Elf64_Verdaux, Elf64_Verneed, Elf64_Vernaux, Elf64_Rel, Elf64_Rela, 64>::rewriteSectionsExecutable() [Elf_Ehdr = Elf64_Ehdr, Elf_Phdr = Elf64_Phdr, Elf_Shdr = Elf64_Shdr, Elf_Addr = unsigned long, Elf_Off = unsigned long, Elf_Dyn = Elf64_Dyn, Elf_Sym = Elf64_Sym, Elf_Versym = unsigned short, Elf_Verdef = Elf64_Verdef, Elf_Verdaux = Elf64_Verdaux, Elf_Verneed = Elf64_Verneed, Elf_Vernaux = Elf64_Vernaux, Elf_Rel = Elf64_Rel, Elf_Rela = Elf64_Rela, ElfClass = 64]: Assertion `lastReplaced != 0' failed.

Do you think it can be fixed ?
