Allow dumpstate to dump auto hal servers

audiocontrol_hal, vehicle_hal and evs_hal were added to dump_util.cpp in
b/148098383. But the coresponding dumpstate.te is not updated to relfect
the changes, causing denials when dumpstate attempts to dump auto hal servers.

This CL updates dumpstate.te to allow dumpstate to access auto hal servers.
