ensure libguestfs mounts are cleaned up

Make a few attempts to umount the libguestfs
mounts, in case other processes are accessing
the mounts (like udev etc.)

If we still can't umount after 5 attempts
(with average delay of about 1s between each),
then initiate a lazy umount so that the mounts
might be automatically cleaned up at some stage.
We wait a further 10s after initiating the lazy
umount, before raising an exception.

Addresses the original issue in bug 1013689
