Make build_id.lo more random (#58258) (#232)
This does not fix the underlying issue that can occur here which is a
collision of build_ids.lo between modules in IR decompression. Fixing
that requires a somewhat significant overhaul to the serialization of IR
(probably using the module identity as a key). This does mean we use a
lot more of the bits available here so it makes collisions a lot less
likely( they were already extremely rare) but hrtime does tend to only
use the lower bits of a 64 bit integer and this will hopefully add some
more randomness and make this even less likely
