Remove static libcutils and libutils dependencies

Bug: 197965342

- libcutils from fluoride_defaults_fuzzable, net_test_device,
net_test_hci
- libutils from bluetoothtbd_test

fluoride_defaults_fuzzable is used by libbluetooth.so which depends on
libchrome.so and libcutils.so.  libchrome.so also has undefined symbols
provided by libcutils.so.

Then:
  ld.lld libcutils.a ... libchrome.so -o libbluetooth.so

fails with upstream lld because the linker tries to define undefined
functions from libchrome.so by fetching objects from libcutils.a.  This
causes undefined symbol errors from libcutils.a since we don't include
other dependencies of libcutils.a here.

Remove this and similarly unnecesary static_lib dependencies from a few
tests and fuzzers.  We need the static libcutils dependence only for the
host libbluetooth.so.

Test: cherry-pick aosp/2036867 and run: mmma packages/modules/Bluetooth
