script.sh: gnupg

[commitay]

Homebrew/brew#4120

The travis pre-installed gnupg is relatively recent but is missing several required dependancies (no idea if they would impact the functionality we need), seems easier just to upgrade it to the current version and install the missing deps which would also mirror the setup that most users have.

If we’re setting HOMEBREW_NO_AUTO_UPDATE earlier, then won’t brew outdated not properly check for the actual latest version?

[commitay]

No, we run brew update as part of before_script.sh

Actually, this won't work because the audit step will also check the gpg signature.

[reitermarkus]

Yes, this should be checked before _audit_modified_casks.

Done.

Not sure what's causing this:

Probably just a temporary network issue.

This seems to be working well with travis now, I've tried several Casks.
