Log:
Initialize offset for adaptive jitter buffer

When the adaptive jitter buffer is enabled in sip.conf, the first frame placed
in the jitter buffer fails with something like:

jb_warning_output: Resyncing the jb. last_delay 0, this delay -215886466,
threshold 1000, new offset 215886466

This happens because the offset is not initialized before calling jb_put(). This
patch modifies jb_put_first_adaptive() to set the offset to the frame's
timestamp.
