The hasBpfSupport() check from BpfUtils is not used by the native helper
in framework. Remove them.

The bpf project now have a new project directory in system/bpf instead
of inside netd. The network related bpf library is renamed to
libnetdbpf. Fix the dependency issue in framework to make sure no
regression.

Add the native implementation for NetworkStatsService to read the
uidStatsMap and tagStatsMap to get the network traffic information.
Currently the implementation only try to get the data from bpf for a
reference but the final value returned is still from old xt_qtaguid
module. So the result will not be effected. The bpf implementation is
depending on libbpf inside netd.

Move the native implementation of TrafficStats to NetworkStatsService
and apps need to get the NetworkStatsService binder interface from
system_server in order to get the network usage stats since boot. This
implementation can hide the detail of retrieving network traffic
information from apps and the NetworkStatsService can choose which
methoed it use to get the data depending on the kernel version of the
device.
