Manage completion permissions through source control (#299)

Remove the executable bit from the completion file: it
is sourced and should never have been executable.

The globbetyglob()/make_scripts_executable() functions,
introduced in ae7bebe ("Add autoconf && ./configure &&
make test_xml replacement", 2007-09-08), are no longer
needed. Executable bits are now managed by version
control, so the functions are removed as well.
