basic: split ifname related calls from format-util.h into format-ifname.h

Browse Source 
This way we don't have to pull in net/if.h into format-util.h.

This is supposed to address https://github.com/systemd/systemd/pull/32212#discussion_r1755639881

No actual code changes, just a .c/.h file split-up.
