Crypt::OpenPGP and gpg conflicts

[timlegge]

Makefile.PL only imports the keys if Crypt::OpenPGP is not installed. Really if gpg is workable it should likely install the keys.

t/3-verify.t does not run any gpg keys if Crypt::OpenPGP is installed. Really it should test for a working gpg install and import the keys if they are missing.

It is also possible that some of these tests should be wrapped in AUTHOR_TESTING
