Bug#963612: Initial packaging done

[Boian Bonev <bbonev@ipacct.com>]

Hi,

Initial packaging is done and included in the upstream repo (
https://github.com/Tomas-M/iotop).

The new iotop-c package is made to support alternatives; also
alternatives patch is proposed to the Python package maintainer in
order for both packages to be able to coexist in the same installation.

Maybe I need to add Conflicts: iotop (version before alternatives)
And maybe there is some other change that I am missing because I am not
very well familiar with Debian's packaging system...

With best regards,
b.
