Add new UCI list 'hostsdir' allowing the usage of the dnsmasq --hostdir
argument while also making sure the path is added to the RO jail for the
dnsmasq process. This is useful e.g. in case of manually maintaining a
set of host-like files that should be monitored for changes that should
be applied immediately. This differers from the --addn-hosts host-like
files which only takes effect after sending a SIGHUP to the dnsmasq
process.
It is important to make sure the directory exists before starting the
dnsmasq process, as any non-existing directory is ignored and won't be
monitored, and a common use-case is to maintain a host-like structure
under /tmp.
