Let linuxulator mprotect mask unsupported bits before calling kern_mprotect.

After r349240 kern_mprotect returns EINVAL for unsupported bits in the prot
argument.  Linux rtld uses PROT_GROWSDOWN and PROT_GROWS_UP when marking the
stack executable.  Mask these bits like kern_mprotect used to do.  For other
unsupported bits EINVAL is returned like Linux does.
