[Xen-devel] [PATCH] mkdeb: use compression level 0

[Wei Liu <wei.liu2@xxxxxxxxxx>]

This requires calling dpkg-deb directly and pass it -z0.

It reduces the time to run the mkdeb script from 14 seconds to 3
seconds on my workstation with SSD, from 87s to 15s on a machine
with HDD. The deb file grows from 49M to 58M.
