* tests/gremlin.scm (%guile-executable): Use /proc/self/exe instead

skipped.
Previously, store items registered in the database by this code (for
instance, store items retrieved by 'guix offload' and passed to
'restore-file-set') would have an mtime of 0 instead of 1.
This would cause problems for things like .go files: Guile would
consider them to be older than the corresponding .scm file, and
consequently it would ignore them and possibly use another (incorrect)
.go file.
