[IPV4]: Staticize and remove unneeded exports.

The patch below contains the following possible cleanups:
- make some needlessly global code static
- remove the following unused global functions:
  - fib_rules.c: fib_rules_map_destination
  - xfrm4_policy.: xfrm4_fini
- remove the following unneeded EXPORT_SYMBOL:
  - tcp_timer.c: tcp_timer_bug_msg
