Turn off -Wnon-virtual-dtor explicitly
adb has been built without -Wnon-virtual-dtor because Soong doesn't turn the flag for the host targets, and the flag can't coexist with -Wexit-time-destructors. However, the new host target linux_bionic_arm64 turns the flag on, because it inherits most of the cflags from the device config. That is forcing us to implement the virtual destructor, which isn't possible due to -Wexit-time-destructors. Solving the issue by explicitly turning -Wnon-virtual-dtor off so that it is disabled also for the linux_bionic_arm64 target.
