Change in coreboot[master]: libpayload: Move .xcompile into $(obj)

[Nico Huber (Code Review)]

Nico Huber has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/47651 )

Change subject: libpayload: Move .xcompile into $(obj)
......................................................................

libpayload: Move .xcompile into $(obj)

And drop the `.`.

Having `.xcompile` in a central place led to race conditions when
multiple payloads try to build their own libpayloads in parallel.
