allows running with aslr and fixes jit..
The memory part MAP_FIXED is to avoid (desired != region) (do not know how that
relates to aslr but with this it runs with aslr), the jit code has to do some
cache sync in order to execute the wirte+exec pages, it was guarded out, and
the problem was masked under w^x because mprotect also does some cache
syncing.. ,thanks Kyle Evans.
Hopefully someone will pick this up for a test. Do not forget bug #275247 Only
tested on aarch64 rpi4 and rk3399.
