[Debian-med-packaging] Bug#1063025: add --clean-build option for building with sbuild

[Andreas Tille]

Hi Praveen,

I admit the --clean-build option is new to me (may be since I'm always
using pbuilder).  I'm happily including a patch if you might want to
provide one for this pretty simple shell script to make sure I will
implement your wish correctly.

Kind regards
   Andreas.
