Bump rtpengine to release 11.5.1.12.
New 11.x release require libopus as a new library and also moved to
PCRE2 library.
Refresh patches and also introduce a new one to disable docs as they
changed doc generation tool and now would require a new prereq and docs
are not useful and would waste space on an embedded scenario.
For recording module libcurl is also now required.
