tests: move the memfd tests over to sys/posixshm

memfd_create is implemented on top of posixshm, so this is a logically
correct place for them to be. Moreover, this reduces the number of places to
look to run tests when working in this part of the tree.

Discussed with:	kib (to some extent, a while ago)
