[Asterisk-code-review] res_rtp_asterisk: Don't assume setting retrans props means to enable. (asterisk[certified/16.8])

Change subject: res_rtp_asterisk: Don't assume setting retrans props means to enable.
......................................................................

res_rtp_asterisk: Don't assume setting retrans props means to enable.

The "value" passed in when setting an RTP property determines
whether it should be enabled or disabled. The RTP send and
receive retrans props did not examine this to know if the
buffers should be enabled. They assumed they always should be.

This change makes it so that the "value" passed in is
respected.
