Disable, Enable GPG signs as needed Pre, Post git am

Disable GPG signing before AM, slows things down and doesn't play nicely.
There is also zero rational or logical reason to do so for these sub-repo AMs.
It's re-enabled (if needed) immediately after, pass or fail.

Given GitHub's recent push for GPG signing, and our own testing, this is not
only helpful, but necessary.
