[PATCH 1/4] package/dnsmasq: permit dhcp_option in global dnsmasq config section

dnsmasq currently permits dhcp_options to be specified only in "config dhcp"
sections of /etc/config/dhcp. When dnsmasq is providing DHCP service for
multiple subnets and there are multiple "config dhcp" sections without "option
ignore", it makes sense to allow dhcp_options that should apply globally in
the "config dnsmasq" section of /etc/config/dhcp. dhcp_option is a list option.

[jow: rework patch to apply after dhcp-option-force handling got introduced]
