Move the bpf ELF binary to system/etc/bpf

The bpf ELF binary caused some conflict in different android builds when
parsing it as a prebuilt binary. This commit changes the type of it into
ETC and move the file from system/bin into system/etc/bpf. And the files
are renamed properly.

Test: make and flash the device, files should present in system/etc/bpf
directory
