unix: unify memory functions on BSD

Make Madvice, Mlock, Mlockall, Mprotect, Msync, Munlock and Munlockall
available equally on all BSD flavors. NetBSD was previously lacking
SYS_MSYNC, so add it.

Reorder the //sys function prototype alphabetically and clean up already
implemented syscalls everywhere.

Also add tests for Mprotect, Msync and Madvice - now that they're
available on all unix platforms.

Fixes golang/go#18513
