style: [tcpip] one-object-per-line formatting in ps2api/ps2ip lists

Reflow the ps2api_OBJECTS, ps2api_IPV4 and ps2ip_OBJECTS lists
in both ee/network/tcpip/Makefile and iop/tcpip/tcpip/Makefile
onto one object per line. Makes future additions (and diffs)
easier to review without changing any compile output — the
installed ps2ip-nm.irx is byte-identical before/after.
