Fix GattToolTest

Found issues that haven't been fixed over time
due to bt_constants being created. Fixing GattToolTest
to properly reflect new location of common variables.

Bug: 73728298
Test: Manually run against Google VR
Change-Id: Idc28fe5fd55cd6ac5f5a2eb1a15830dcdaf905ed
(cherry picked from commit a9c42c49a30d49a7a4380e9477920f5c3e1ad2e6)
