[PATCH] t/nntpd: do not fork on indexing, test v2

[Eric Wong <e@yhbt.net>]

No need to waste resources when doing minimal work.  With
PI_TEST_VERSION=2, this fixes a test failure where
Net::NNTP::DESTROY was getting called in the shard process.

We'll also get rid of an unnecessary use_ok under v2, too.
