MTK final RIL fix

[Deepflex]

For some users of MTK devices problem with RIL is still here, they are have connection and etc / but it is very unstable, SMS and MMS can't be sended + all time cignal is empty at status bar. Following lines solve problem

Some mtk devices(newer socs) have libmtk-ril.so instead of mtk-ril.so

[Deepflex]

Yes :) MTk devices use mtk-ril and librilmtk This sollution is fully working :) Checked on my MTK devices with mtk-ril and librilmtk in vendor :)

[Dinolek]

librilmtk.so is used by all, mtk-ril.so(without lib have only older socs) and libmtk-ril(with "-" have only newer socs).

I think this is a better place

[phhusson]

well, I must say, I can't see how doing

setprop rild.libpath mtk-ril.so
setprop rild.libargs -d /dev/ttyC0

right before rebooting would do anything since they are non-persistent properties
