[PATCH] virCommand: Extend debug message for handshake

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Currently, we are logging only one side of pipes we
create in virCommandRequireHandshake(); This is enough
in cases where pipe2() returns two consecutive FDs. However,
it is not guaranteed and it may return any FDs.
Therefore, it's wise to log the other ends as well.
