tests: check decoding of new FRA_* netlink attributes

Browse Source 
* configure.ac (AC_CHECK_TYPES): Check for struct fib_rule_port_range
in <linux/fib_rules.h>.
* tests/nlattr_fib_rule_hdr.c: Include <linux/in.h>.
(FRA_PROTOCOL, FRA_IP_PROTO, FRA_SPORT_RANGE, FRA_DPORT_RANGE): New
macro constants.
[!HAVE_STRUCT_FIB_RULE_PORT_RANGE] (struct fib_rule_port_range): New
type.
(main): Check decoding of new FRA_* netlink attributes.
