* Remove "auto" and "guess" as synonyms for 0 in the handling of

build-cores and --cores.  They're superfluous and just complicate
  the parsing.

### Option `build-cores'
#
# This option defines the number of CPU cores to utilize in parallel
# within a build job, i.e. by passing an appropriate `-jN' flag to
# GNU make. The default is 1, meaning that parallel building within
# jobs is disabled. Passing the special values `0', `auto', or
# `guess' causes Nix to try and auto-detect the number of available
# cores on the local host. This setting can be overridden using the
# `--cores' command line switch.
