  [scudo] Select stricter atomic memory_order in MemMapFuchsia

Previously, all operations were relaxed except for the
atomic_compare_exchange call, which was implicitly acquire (but did not
compile anymore because of the changes in commit
3ef766addadd8324f58c0fda0301edcde2185cb3).

In addition to making MemMapFuchsia compile again, this CL selects
memory_order values that better express the intent of the code.
