tests: avoid spurious failure when running as root

Fixes automake bug#12041.

* t/primary-prefix-couples-force-valid.sh: If run as root, don't expect
a "test -x" on a non-executable files to fail: for root, all files are
executable (as well as readable and writable), and at least on Solaris
10 that causes "test -x" to succeed also on non-executable files.
