xen/lzo: Remove more remanants of TMEM

This logic was inserted by commit 447f613c5404 ("lzo: update LZO compression
to current upstream version") but was only relevant for the TMEM logic, so
should have been deleted in commit c492e19fdd05 ("xen: remove tmem from
hypervisor")

Fixes: c492e19fdd05 ("xen: remove tmem from hypervisor")

Notably, this also removes the singular case where anything in Xen cares about
the value in __BYTE_ORDER, __LITTLE_ENDIAN and __BIG_ENDIAN, and even then it
was only an adaptation to the MiniOS environment.

v5:
 * New.
