The log_call helper is now accepting a time parameter (dictionary). If
the param is not None, the function will fill the timing indications
(user and system time) for the TestCase.
There are some TestCases whose user time is not of our interest; for
example we don't really care about the cpu time of a stdout diff
(MatchStdout tests). In those cases the resulting cpu time in the
generated JUnit file (results.xml) will be 0.

Added utility class `TimedWaitPID` which monkey-patches os.waitpid()
with a functor that has the same signature, but calls os.wait4()
instead. This allows the process's user and system CPU time to be
obtained from the OS when using APIs (such as subprocess) which use
os.waitpid() internally.
The process CPU time is stored within the functor and can be read back
later by calling TimedWaitPID.get_time_for_pid().
