Tony Ambardar 3e9d639e8f iproute2: separate tc into tiny and full variants
This change was investigated previously [1] but not deemed necessary. With
the recent addition [2] of modern BPF loader support, however, tc gained
dependencies on libelf and libbpf, with a larger installation footprint.

Similar to ip-tiny/ip-full, split tc into tc-full and tc-tiny variants,
where the latter excludes the eBPF loader, uses a smaller executable, and
avoids libelf and libbpf package dependencies. Both variants provide the
'tc' virtual package, with tc-tiny as the default.

The previous tc package included a loadable module for iptables actions.
Separate this out into a common package, tc-mod-iptables, which both
variants depend on. Some package sizes on mips_24kc:

Before:
  148343  tc_5.11.0-1_mips_24kc.ipk

After:
  144833  tc-full_5.11.0-2_mips_24kc.ipk
  138430  tc-tiny_5.11.0-2_mips_24kc.ipk  (and no libelf or libbpf)
    4115  tc-mod-iptables_5.11.0-2_mips_24kc.ipk

Also fix up some Makefile indentation.
