BpfProgs: timeInState: enable libbpf
This change ports timeInState to libbpf APIs.
This program successfully loads with BpfLoader.rs, permissions validated
by running 'ls -alh /sys/fs/bpf' on with this change set and comparing
with an unmodified cuttlefish instance.
This will open the path to deprecating the uid_sys_stats out of tree
kernel driver, as we will be able to use CO-RE to access the task
struct.
