libraries/<HAL>/hwdef/... changes were being tagged with the HAL library
name (e.g. AP_HAL_ChibiOS) since it was listed before hwdef as a
candidate subsystem, and an already-declared HAL name was treated as
valid and left alone. Make hwdef -- the deepest directory in the path --
the canonical tag in both cases, since it applies uniformly across
every HAL rather than being tied to one library.
