hostapd.te

It appears that wpa_supplicant tries to rmdir /data/misc/wifi/sockets
and re-create it at times, so make sure that it remains labeled correctly
when re-created in this manner via a name-based type transition rule.
Do the same for hostapd as it also has permissions for creating/removing
this directory.

We no longer need the type_transition for sock_file as it will inherit
the type from the parent directory which is set via restorecon_recursive
/data/misc/wifi/sockets or via type_transition, so drop it.
