dnsmasq: enable pxe-prompt, pxe-service config options

DNSMASQ has the ability to provide a menu to a pxeboot system, using
the --pxe-prompt and --pxe-service configuration options.  The current
init.d script converting the "dhcp" file to "dnsmasq.conf" does not
find these options, but they are supported.  This patch thus enables
the options.
