be more restrictive in what 00compile.t tests

[Yitzchak Scott-Thoennes]

I'm working on adding EU::CBuilder and EU::ParseXS to the core, which
involves adding a file:

lib/ExtUtils/ParseXS/t/XSTest.pm        Test file for ExtUtils::ParseXS tests

Unfortunately, makemaker's 00compile.t blithely tests all *.pm files in
the ExtUtils hierarchy, and XSTest doesn't pass (since it's corresponding
XSTest.xs is only built during the ParseXS test).

A patch to skip files in t subdirs:
