config/reader: Fix build error when WITH_LB is disabled.

Add -I command line parameter (set syslog ident).

With -I user can set the ident used by oscam when logging to syslog.
The default ident is "oscam".

Add -B command line parameter (set pidfile name).

Using -B sets pidfile name and takes precedence over pidfile= setting
in [global] section of oscam.conf.

Now you can run oscam as proper daemon by executing:

   `oscam -c conf_dir -b -B oscam.pid`
