dhcpcd: Apply local modifications

* The modification to 'src/if.c' makes it can be build with
'-Werror=implicit-fallthrough', which is enabled with '-Wextra'.
However, both swildner and I still don't understand why such a
modification is needed :(

* In 'src/ipv6.c', explicitly suppress the '#warning' on
IPV6_POLLADDRFLAG, an IPv6 feature that dfly currently doesn't
support.
