[PATCH BlueZ v1 3/4] tools/gap-tester: Enable hciemu debug output

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Add print_debug callback and call hciemu_set_debug when debug output is
enabled so that hciemu error paths are visible during test runs.
