[PATCH] cvs tests: When root, skip tests that call "cvs commit"

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the tests that fail to when we run the test suite as root, due
to calling "cvs commit".

The GNU cvs package has an optional compile-time CVS_BADROOT
flag. When compiled with this flag "cvs commit" will refuse to commit
anything as root. On my Debian box this isn't compiled in[1] in, but
on CentOS it is.

I've run all the t/t*cvs*.sh tests, and these are the only two that
fail. For some reason e.g. t9402-git-cvsserver-refs.sh still works as
root despite doing "cvs commit", I haven't dug into why.

This commit is technically being overzealous, we could do better by
making a mock cvs commit as root and run the tests if that works, but
I don't see any compelling reason to bend over backwards to run these
tests in all cases, just skipping them as root seems good enough.

1. Per: strings /usr/bin/cvs|grep 'is not allowed to commit'
   Using cvs 1.11.23 on CentOS, 1.12.13-MirDebian-18 on Debian.
