[Tizen][OBS] Changes for Tizen OBS Build

[Issue]
OBS build does not support running script 'build_{target].sh'.

1) GBS Build Options
In OBS build, definitions, coming through gbs build option, can NOT be used,
such as 'chromium_efl_tizen_version'.

2) Package Name
In OBS build, using macros around property 'Name' in spec file is not allowed.

3) Supplementary Repository
In OBS build, the supplementary repository is not allowed.

[Resolve]
1) GBS Build Options
The definitions, coming through gbs repository, are used,
instead of the definitions coming through gbs build option.

2) Package Name
In Tizen v3.0, appid should be consist of '.',
but package name doesn't need to follow that rule.

3) Supplementary Repository
The supplementary repository is removed in the file 'gbs.conf'.
Currently, chromium-efl doesn't have dependency of supplementary repository.
