tools: remove SIGUSR* handling from gst-launch

Browse source 
Remove SIGUSR* handling from gst-launch, since it might interfere
with other things (e.g. libleaks), and should be done differently
anyway (either via support for simple timed-commands scripting or
remote control via DBus or so).

.SH "PIPELINE CONTROL"
A pipeline can be controlled by signals. SIGUSR2 will stop the pipeline
(GST_STATE_NULL); SIGUSR1 will put it back to play (GST_STATE_PLAYING).
By default, the pipeline will start in the playing state.
.br
There are currently no signals defined to go into the ready or pause
(GST_STATE_READY and GST_STATE_PAUSED) state explicitely.
.SH "PIPELINE EXAMPLES"
The examples below assume that you have the correct plug-ins available.
