conf: Rework checking for garbage after a rangeHEADmaster

After parsing port ranges conf_ports_spec() checks if we've reached a
chunk delimiter (',') to verify that there isn't extra garbage there.
Rework how we do this to use the recently introduced chunk-end
pointer.  This has two advantages:

1) Small, but practical: we don't need to repeat what the valid delimiters
   are, that's already handled in the chunk splitting code.

2) Large, if theoretical: this will also give an error if port parsing
   overruns a chunk boundary.  We don't really expect that to happen,
   but it would be very confusing if it did.  strtoul(3), on which
   parse_port_range() is based does say it may accept thousands
   separators based on locale which means we can't be sure it will
   only accept strings of digits.
