Adds some instrumentation to uprobes2/uprobes.c (AKA uprobes_core.c)

I'm not seeing any hangs, but I see the Trace/breakpoint trap on [2].

And when I add the attached instrumentation to uprobes[_core].c, I see lots of
printks ("Child %d failed to inherit parent %d's SSOL vma..." and "Parent %d's
SSOL vma is no longer valid...") on [4] -- but not [2].  I haven't yet figured
out why that happens.
