donate-cpu.py: Add internal timing information of Cppcheck to output (#2217) 
* donate-cpu.py: Add internal timing information of Cppcheck to output

The option "--showtime=top5" is added to the Cppcheck command line.
The timing output is collected and only for HEAD it is shown in the new
category "head-timing-info" in the results output.
The timing output is indented with one white space, so even in the
unlikely case that a function is named "head result:" or "diff:" it does
not break the parser in the server.

* donate-cpu.py: Also print the "old" timing information for comparison
