The mremap06 test relies on being able to move a mapping into the unmapped space of an existing reservation (second call to mremap() in do_test()). This is explicitly disallowed in PCuABI (for all syscalls that can create mappings), and it is unclear if the original bug can be reproduced if remapping to another adddress, so let's just skip the test when running in purecap, at least for now.

Merged into next. Thank you.
