Unlock the pledge(2) system call
Protect the ps_pledge/ps_execpledge fields with ps_mtx. Shuffle the
code to call unveil_destroy() outside the critical section. Only writes
to those fields are protected. Since we may only remove bits from those
fields, garbage values should do no harm even when a read crosses
a write on 32 bits systems.
