xen-rpi-u-boot-scr: WORKDIR -> UNPACKDIR transition

Borrowed from Leon Anavi <leon.anavi@konsulko.com>
meta-raspberrypi: commit 434ed33c90b7659152b1e8d7c2d4d785db85105f

and from Martin Jansa <martin.jansa@gmail.com>
meta-raspberrypi: commit c39c2b165e68388767f54dc86acf4595a33ee1e1

This adapts to the oe-core rework to enforce a separate directory
for unpacking local sources (UNPACKDIR) instead of directly using
WORKDIR.

Follows the preliminary guideline from:
