sms: punt handling of 8-bit encoded SMSs to clients

There's no encoding information about 8-bit SMS messages,
and they are often binary things like ringtones or voicemail
indicator commands.  Since there's no point to our parsing
them just let clients deal with it.

BUG=chromium-os:22200
TEST=src/test-sms from build, run on device (a test with the 8960 is under development)
