tracing: Update function tracing output for previous boot buffer
For a persistent ring buffer that is saved across boots, if function
tracing was performed in the previous boot, it only saves the address of
the functions and uses "%pS" to print their names. But the current boot,
those functions may be in different locations. The persistent meta-data
saves the text delta between the two boots and can be used to find the
address of the saved function of where it is located in the current boot.
