remove symbols from greylist

telephony-common is not intended to used by any apps and
being in boot class is not updatability friendly.
We are removing telephony-common from bootclass and apply
<uses-library> in manifest instead.
for apps targeting < R will auto load telephony-common lib
for app compatibility. For apos >=R, only allow usage for
phone UID.
