x86/boot: Drop incorrect mapping at l2_xenmap[0]

It has been 4 years since the default load address changed from 1M to 2M, and
_stext ceased residing in l2_xenmap[0].  We should not be inserting an unused
mapping.

To ensure we don't create mappings accidentally, loop from 0 and obey
_PAGE_PRESENT on all entries.
