Please also support debian gbp

[rzr]

Debian git-build-package is clashing with tizen version, it would be nice to have tizen adaptation merged upstream and then use a single gdp.

Somehow this repo for gbp is in deprecated status, please go tizen.org infras(including gerrit, JIRA, etc) to contact current maintainers for more support. Sorry for the inconvenience.
