valgrind: Use --trace-children=no --child-silent-after-fork=yes

Browse Source 
When we are valgrinding we don't really care about the child
processes, which might be qemu, libvirtd, etc.  So disable tracing
into children (at least, as far as is possible with valgrind, which is
not entirely disabling it, but suppressing it).
