siproxd: update to version 0.8.3, improve logging and memory usage

This release includes bug fixes and improvements accumulated over the last
4 years of development snapshots [1].

Bump upstream version, build new plugins 'stats' and 'blacklist', and add
an 'sqlite3' package dependency for siproxd-mod-blacklist.

Disable procd capturing stderr to syslog, since siproxd in 'foreground'
mode writes both to syslog and stderr, duplicating log messages.

Include a patch to drastically reduce memory usage (RSS from 17MB to 5MB
on ipq40xx platform):

  * 005-reduce-rtpproxy-urlmap-size.patch

Drop the following patches now included upstream:

  * 010-syslog-msg.patch
  * 100-musl-compat.patch
