tools subcmd: allow parsing distinct --opt and --no-opt

libsubcmd automatically generates for every option --opt an equivalent
negated option, --no-opt, to unset the option. Vice versa, for every
option declared as --no-opt, a shorthand --opt is declared for
convenience.

Add a flag, PARSE_OPT_NOAUTONEG, to disable this behavior. This new flag
behaves similarly to the already existing PARSE_OPT_NONEG, only it does
not reject the --no-opt variant, but leaves it undefined. That is useful
when there is a conflicting distinct --no-opt option in the syntax of
the tool.

PARSE_OPT_NOAUTONEG is enabled per-option, allowing to unset other
options that do not have this conflict.
