Revert "Set both legacy and new UID routing attributes."

Goes with Revert "Use new-style UID routing."

- Apparently, the latest AOSP-CAF tag requires the kernel to be compiled
  with CONFIG_ARPD=y. (This should be avoided by removing CONFIG_ARPD
altogether and is done in upstream).

- I haven't deciphered the exact reason why it's needed because on other
  AOSP / LineageOS, we can dump ARP tables without CONFIG_ARPD=y.

- The new UID style routing isn't compatible with older phones running
  3.4 kernels and hence probably requires additional ported TCP / IP stack
  (similar to what's done in Bullhead / Sailfish - Android O / Master).

This reverts commit 58b125cf3a1e1853170063d12ad8d16a63be2f39.
