THRIFT-373. Get some missing files into the release tarballs

- Added some stuff to EXTRA_DIST.
- Added some non-compiled sources to a C++ test.
- Made lib/perl/test a SUBDIR of lib/perl.

The last is a revert of r766558, but I moved the "Types.pm" rules in
lib/perl/test/Makefile.am to the check-local target, so it should still
work as expected (per THRIFT-461).
