When partial cleanup messes up the guestfs cache, the call to guestmount
will fail. To fix that, let's check if there is a problem first and
clean up everything if needed.

We can use a key function instead of relying to the deprecated cmp. This
makes the code work on Python 2.6 and on recent versions it makes it
faster.

This will automatically convert the output to unicode/str and we will
not have to worry about decoding ourselves.

Occasionally we have seen the mount command fail. The default error
message says to set some environment variables and try again. We can
just always set the environment and only print the output on failure.

This patch refactors logic for creating a temporary mount point,
mounting an image, running arbitrary code on it, unmounting the image
and removing the mount point. It immediately uses it in the buildinstall
phase.
Similar mounting is present in product_img phase as well, but due to
different usage pattern it's not changed yet.

If the checkisomd5 command exits successfully but returns a wrong value,
we should catch and log that. In theory this should be impossible, but
we have seen it in production.
