libnetdutils is referenced by netd.c and TrafficController.cpp, which are going to be mainlined. Therefore, move libnetdutils to a common place where both mainline module and platform code (Netd) can refer to. Bug: 202086915 Test: build; flash; cd system/netd; atest Ignore-AOSP-First: the netd change(same topic) would not automerge from aosp. No-Typo-Check: Clean code move with no other changes. BYPASS_INCLUSIVE_LANGUAGE_REASON=Clean code move with no other changes. Change-Id: I645bfe35f6543149c9a9f894cd4158d27a481abe
