Don't pass --disable-command-args to configure.

See options.mk, in the case without options nagios-nrpe-args:
# Upstream's configure enables command args when given
# "--disable-command-args", so (departing from pkgsrc norms) don't
# give the --disable option.

PKGREVISION++; the previous version enabled command args when it
should not have.
