lib/oe/patch: add user and email when patchtool is git

When the PATCHTOOL=git, oe-core creates a git repo for the sources with:

 git init
 git add .
 git commit

The git commit can fails blindly due to misconfigured user when git don't have
the email proper configured. Although the commit command does not fail
because it returns 0, it is not executed and the tree remains with all
files staged so the following git commands can fail and fails in some cases.

This problem has been particularly observed in some obscure and little-used
cases in openembedded-core like patching the linux-firmware which only works
using PATCHTOOL=git because it deals with binary files.
