t3070: Disable some failing fnmatch tests

The failing tests make use of a POSIX character class, '[:xdigit:]'
in this case, which some versions of the fnmatch() library function
do not support. In the spirit of commit f1cf7b7 ("t3070: disable
unreliable fnmatch tests", 15-10-2012), we disable the fnmatch() half
of these tests.
