fgraph: Use fgraph data to store subtime for profiler
Instead of having the "subtime" for the function profiler in the
infrastructure ftrace_ret_stack structure, have it use the fgraph data
reserve and retrieve functions.
This will keep the limited shadow stack from wasting 8 bytes for something
that is seldom used.
