[PATCH] t: avoid "subtest" for Perl 5.10.1 compatibility

[Eric Wong <e@80x24.org>]

The version of Test::More from Perl 5.10.1 did not support
"subtest", and the earliest version which did is Perl 5.12.0

The good news is this gives me an excuse to parallelize
the indexlevels-mirror test by splitting it into two.
(it could be further split, even).

Update t/nntpd. to use PI_TEST_VERSION consistently while
we're at it.
