[mrtg] cfgmaker not quoting --if-filter in "Created by" lines

[Joe Moore]

I've noticed that when I specify "--if-filter='$default_iftype'" to 
cfgmaker, the resulting cfgfile doesn't have the if-filter argument 
quoted.  (in the second line)

This plays havoc with the script I've written to re-generate the config 
files (to pick up interface alias changes, etc)

To get around this, I've added '\$' to the list of to-be-escaped 
characters for $opt{fullcmd}.  While this doesn't exactly give an 
aesthetically pleasing result (the entire --if-filter argument is 
quote-escaped), it is functionally acceptable for my script.
