telephony: disable the use of SMS_EXPECT_MORE by default (1/2)

CodeAurora added the use of the RIL_REQUEST_SEND_SMS_EXPECT_MORE API
which is not supported by every RIL. Disabled it by default to reflect
AOSP behavior and added a flag to enable it.

VolumePanel: Don't force navigation bar

It always annoyed me that when changing volume while in immersive the navigation bar is shown.
