audio: Record uplink voice after echo cancellation

In current design, incall uplink recording is same as normal
audio recording. Some downlink data is also recorded since
there is no echo cancellation(EC) algorithm applied.
-To fix the issue, the tapping point will be moved to the point
between vocproc and encoder, because EC is applied in vocproc
module.Add voice uplink verb and modifier definition.
During voice uplink recording, use uplink verb and modifier,
instead of audio recording verb and modifier.
