fortify: Improve buffer overflow reporting
Improve the reporting of buffer overflows under CONFIG_FORTIFY_SOURCE to
help accelerate debugging efforts. The calculations are all just sitting
in registers anyway, so pass them along to the function to be reported.
For example, before:
detected buffer overflow in memcpy
and after:
memcpy: detected buffer overflow: 4096 byte read of buffer size 1
