Make configure check for a couple more Perl modules for --enable-tap-tests.

Red Hat's notion of a basic Perl installation doesn't include Test::More
or Time::HiRes, and reportedly some Debian installs also omit Time::HiRes.
Check for those during configure to spare the user the pain of digging
through check-world output to find out what went wrong.  While we're at it,
we should also check the version of Test::More, since TestLib.pm requires
at least 0.87.

In principle this could be back-patched, but it's probably not necessary.
