service: We dont need to serve 'compcache'

'compcache' is service introduced in CM based ROMs.
This service is nothing but zram initializer.

This service is FAILURE for CM ROMs with CM Kernel as they havent enabled ZRAM via config for N7000/I9100.
NX-Kernel has enabled ZRAM and SWAP in config.
However, NX-Kernel has perfect and user-controlled ZRAM management.
