[PATCH] init.sh: accomodate directory with no .exes

[Eric Blake]

Cygwin was failing test-vc-list-files-{cvs,git}.sh, because of
spurious output on stderr.

../../tests/test-vc-list-files-cvs.sh (exe_shim): skipping directory: 
/home/eblake/m4-branch/build-aux

All because build-aux was a directory containing just scripts, and
no .exe extensions.  This fixes it.

* tests/init.sh: Accomodate directory containing only scripts.
