dvblast: Add -g/--logger-ident parameter to set syslog ident.

By default dvblast uses program name (argv[0]) as syslog
ident. This is fine but a little hard to find. So in order
to be easier to choose syslog ident add -g/--logger-ident
parameters to resolve this. If one of the parameters is not
set argv[0] is used instead.

 .SH DESCRIPTION
 DVBlast is a simple and powerful streaming application based on the linux-dvb API.
 It opens a DVB device, tunes it, places PID filters, configures a CAM module, and demultiplexes the packets to several RTP outputs.
