build-system/gnu: Do not patch symlinks in the source. 

This is a followup to 13a9feb5b64fd819eaed38a17da0284bbe2b8d9.

* guix/build/gnu-build-system.scm (patch-source-shebangs): Remove call
to 'remove'.  Pass a second argument to 'find-files' to filter out
symlinks; pass #:stat lstat.
(patch-generated-file-shebangs): Likewise, and also filter out
non-executable files.
