busybox: Guard against interrupted compiles 

If busybox is interrupted during do_compile, it can corrupt .config with
the suid version, or worse. Typically this leads to files disappearing,
particularly /etc/init.d/* which leads to an empty busybox-hwclock.
That then results in errors at do_rootfs time due to the missing package.

The fix is to use any 'orig' present to restore stat at the start of
compile.

(From OE-Core rev: 601abb497531823a73bdec3baf56952086e5b4f4)
