oeqa/selftest/signing: Skip tests if gpg isn't found

Raising an assertionError in the class setup isn't a particuarly good way to
indicate gpg isn't installed. Instead skip the tests if the required binary
isn't present. For the signing tests we do require it to be present and can't
use a prebuilt one.
