Bug 9843: Include OpenILS directory in Perl lib directory

When installing from the tarball, the OpenILS/QueryParser.pm file seems
to be missed because it is not included in Makefile.PL... sometimes.

To test:
1) Run Makefile.PL and make.
2) Look in blib/PERL_MODULE_DIR/ and check if the OpenILS directory is
   there.
3) Apply patch.
4) Rerun Makefile.PL and make.
5) Confirm that OpenILS directory is now in blib/PERL_MODULE_DIR/
   regardless of whether or not it was there during step (2).
6) Sign off.

Note: Confirmed that OpenILS directory is correctly installed in the lib dir,
in 'standard' install mode, and also 'single'.
