* keygen.c (make_backsig, write_direct_sig, write_selfsigs)

Browse Source 
(write_keybinding): Have the various selfsigs created during key
generation use the timestamp of their parent key.  This helps avoid
leaking information about the performance of the machine where the
keys were generated.  Noted by Christian Danner.
