t9700: loosen ident timezone regex

A few of the perl tests in t9700 ask for the author and committer ident,
and then make sure we get something sensible. For the timestamp portion,
we just match [0-9]+, because the actual value will depend on when the
test is run. However, we do require that the timezone be "+0000". This
works reliably because we set $TZ in test-lib.sh. But in preparation for
changing the default timezone, let's be a bit more flexible. We don't
actually care about the exact value here, just that we were able to get
a sensible output from the perl module's access methods.
