Subject: [PATCH] pull requests: use a meaningful branch when building

This change makes the build runner switch to a meaningful branch name, which will then appear as the "Firmware Branch" in the System Info of the web application. This helps users testing pull-request builds identify that they are actually using the changes from the respective pull request.
