Move file-set and hash-triple modules to gnulib.

* bootstrap.conf (gnulib_modules): Remove file-set, now that
it's in gnulib, and the canonicalize module requires it there.
* gl/lib/file-set.c, gl/lib/file-set.h, gl/modules/hash-triple: Remove.
* gl/lib/hash-triple.c, gl/lib/hash-triple.h, gl/modules/file-set: Remove.
