Use static inline for iface_{setup,delete}_addr in tests/sys/net/routing.

This fixes possible link errors, similar to:

ld: error: undefined symbol: iface_setup_addr
>>> referenced by test_rtsock_l3.c:111 (tests/sys/net/routing/test_rtsock_l3.c:111)
>>>               test_rtsock_l3.o:(presetup_ipv4)

In C (not C++), 'naked' inline is almost always a mistake. Either use
static inline (this is appropriate for most cases), or extern inline.
