payloads/ipxe/makefile: Use git checkout for resetting config state

At the moment copies of the original configuration files are created
before customisations are applied and the state is reset by copying them
back after the build finished, so that the state is not left dirty when
another build is done. That's not just overly complicated but it also
doesn't allow debugging the state after the build finished and the state
is left dirty when the build gets interrupted in between.

Simplify resetting the state by using `git reset --hard` before config
customisations are applied, which makes the file copies superfluous and
it also leaves the tree dirty after the build.
