res_fax: Warn that minrate=2400 is not valid for V.27 instead of failing load.

Browse Source 
Change minrate from 2400 to 4800 on config reload in response to changes from
ASTERISK-22790 only.  Any config with minrate of 2400 that would fail before
r405693 will still fail.

Comment out many settings in res_fax.conf.sample. The defaults are set in
res_fax.c, so setting the same value in sample config does nothing but make
the sample config more fragile.
