[LTP] [RFC PATCH 1/2] lapi: Create if_addr.h and reuse it in rtnetlink.h

[Petr Vorel <petr.vorel@gmail.com>]

There will be fix in next commit for missing IFA_F_NOPREFIXROUTE which
requires creating lapi/if_addr.h. Thus move IFA_FLAGS to lapi/if_addr.h,
as it belongs there and reuse lapi/if_addr.h in lapi/rtnetlink.h just
like <linux/rtnetlink.h> includes <linux/if_addr.h>.
