Use stubs generated by build system

instead of hand-crafted stub for libnetd_resolv apex.

This change doesn't affect to the Q-device compatibility because netd on
Q device can still the hand-crafted stub for libnetd_resolv.so and the
shared library is not changed.

Bug: N/A
Test: m && flash && boot
Test: adb shell ldd /system/bin/netd # shows libnetd_resolv.so from apex
