Ungoogled-chromium: Update version string

[steven-omaha]

The version string in chromium --version should reflect that one is running ungoogled-chromium, not vanilla chromium.

I would be okay with appending the ungoogled-chromium version, but I don't want to change the existing string. I'd also prefer to have it set through CHROME_VERSION_EXTRA instead of through the source code to make it easier to implement.

ungoogled-chromium should have it's own identity because it's a lot more than just few patches

[webbertakken]

besides the version string from chromium --version it is also displayed under about, saying (Official build).

[Eloston]

@webbertakken Yes. Debian's chromium package (and also ungoogled-chromium's Debian packages) use these environment variable to set the Debian versions used for building and running.

I would like to tackle this one. Any tips about how to proceed?

@mintunitish You basically need to get the ungoogled-chromium version info from version.ini via get_package.py. One simple way to do this is to add a .ungoogin file that will contain only the ungoogled-chromium version, and then modify the Chromium launching wrapper scripts to modify CHROME_VERSION_EXTRA with the value from this file. How you modify the packaging scripts depends on the packaging scripts you modify.
