[usb][mediatek] Fix thread teardown race.

Currently, zx-primitives are being used to synchronize the halting of a
processing thread.  This is racy if the containing object is being
deallocated.  This replaces the primitives with a call to thrd_join(),
which fixes the race.  This seems to only affect clang-x64 builds.

FLK-244 #done

Test: runtests -t mt-hci-endpoint-test-test -r 1000 (~3% racy before)
