Set path correctly for PERL_CORE

[jkeenan]

One of the major changes introduced in perl-5.28 in 2018 was a security fix which caused directory . to no longer be automatically included in @INC. Prior to that production release, we had to make certain workarounds in an important component of the Perl 5 testing infrastructure, t/TEST, to accommodate three CPAN distributions which are shipped with the Perl 5 core distribution.

The Filter distribution was one of those three. We would like to be able to remove the workaround from t/TEST. To that end, I am submitting this pull request which includes revisions to the BEGIN block in two files and which I have tested successfully both in core and in a git checkout.

If these changes are satisfactory, we would appreciate a new CPAN release of Filter so that we can then synch it into Perl 5 blead.

Thank you very much.

The description is wrong. Can you change it to "push Cwd to @INC in 2 tests" or something like that? There is no path fixed.
And I'll check if Cwd is really a good idea. Normally you just need to add . to @INC.

Done.
