[PATCH V2] sanity: add function to check for git config user

[Stephano Cetola <stephano.cetola@linux.intel.com>]

If attempting to patch a git repo without a proper git config setup,
an error will occur saying user.name/user.email are needed by git
am/apply. After some code was removed from kernel-yocto, it was
simple enough to reproduce this error by creating a kernel patch and
using a container to build.

This patch abstracts out functionality that existed in buildhistory
for use in other classes. It also adds a call to this functionality
to the kernel-yocto class.

Fixes [YOCTO #10346]
