On my previous commit I made the wrong assumption that the control socket was
being unlink(2)ed from the main proc so I removed "cpath" from the pledge(2) on
the ldpe proc but actually the socket was unlink(2)ed from here, this means the
daemon would crash on exit due to pledge(2) not having "cpath" permissions
anymore. Finish the job by just not deleting the socket at all during
control_cleanup(), which keeps the control program still working without issues
but more importantly prevents the crash during exit, sorry about that.
Crash reported by wlund at iki.fi
