Dual-lived Cwd.pm problem again on Fedora, test failed with SHIPWRIGHT_TEST_EXTRA=1

[cheese]

Fedora uses the Cwd.pm from PathTools CPAN distribution and places it to
/usr/lib64/perl5/vendor_perl/ .

So if some procedure deletes this path, it will fail to find this module.

Tested Shipwright-2.4.36.

+ make test SHIPWRIGHT_TEST_EXTRA=1 -j8
