system.conf.sample: Remove reference to single frequency signalling.

Single frequency signalling has not been supported in dahdi_cfg since the switch
to DAHDI. Before DAHDI, in the Zaptel days, it was only suported in the
ztcfg_dude utility which wasn't mainlined. So this removes references to those
signalling modes unless support is added back into the driver.

# Channel(s) are signalled using FXO Koolstart protocol.
# sf::
# Channel(s) are signalled using in-band single freq tone.
# Syntax as follows:
# channel# => sf:<rxfreq>,<rxbw>,<rxflag>,<txfreq>,<txlevel>,<txflag>
# rxfreq is rx tone freq in Hz, rxbw is rx notch (and decode)
# bandwith in hz (typically 10.0), rxflag is either 'normal' or
# 'inverted', txfreq is tx tone freq in hz, txlevel is tx tone
# level in dbm, txflag is either 'normal' or 'inverted'. Set
# rxfreq or txfreq to 0.0 if that tone is not desired.
# unused::
# No signalling is performed, each channel in the list remains idle
