rdup 1.1.15

- 1.1.15 includes parallelization and HAVE_DIRFD fixes
- author now distributes the release as a source archive on GitHub
- switch homepage to GitHub since author's site no longer has rdup info
- `autoreconf` required because source archive doesn't include configure
- run `make check` optionally by passing `--with-test`

Closes Homebrew#49674.
