otter: init.omap4430.rc: use entropy files for p2p_supplicant/hostapd services

This will prevent disconnects for the first few times while connecting
to an encrypted AP or GO. Otherwise the EAPOLs fail because of
insufficient entropy.

otter: init.omap4430.rc: don't use driver_params in the wpa_supplicant command line

These override the ones given in wpa_supplicant.conf, causing extra
parameters to be discarded.
Since it is easier to control wpa_supplicant.conf (not read only), use
only parameters there.
