createrepo: Disable GPG signature validation

If the packages are signed, and the signature is not in the rpm-native
RPMDB, an error will occur.  We want to avoid this failure mode 
when building the native version of createrepo.

This only affects the feed generation and will not change any later
validations during use/install from the package feed.

Upstream-status: Inappropriate [no longer maintained version]
