build: meson: fix setting iptables/dnsmasq/dnssec-trigger paths

Browse source 
Handle the iptables, dnsmasq and dnssec-trigger paths in the same way
through common code.

The path set by user must be accepted as is, even if does not exist,
because this is a requirement for cross-compilation. When user does
not specify a path, search a predefined set of paths and fall back to
an hardcoded one.
