7022204: LogFile wildcarding should use %p instead of star
Reviewed-by:

Currently to get wildcarding in the LogFile name you have to use *
which is very unfriendly for shell scripts.  We should use %p as we do
in other places.  It still accepts * and will convert it in preference
to %p.  I considered switching to using Arguments::copy_expand_pid but
it would change the behaviour of the flag in an incompatible way so I
just augmented the existing logic slightly.  Tested with various
command line flags
