util: add disk_cache_get_function_identifier()

Browse source 
This can be used as a drop in replacement for
disk_cache_get_function_timestamp().

Here we use build-id to generate a driver-id rather than build
timestamp if available. This should resolve issues such as
distros using reproducable builds and flatpak not having
real build timestamps.
