Name the branch on package build page

[riastradh]

The page for a package build, such as https://releng.netbsd.org/bulktracker/pkg/17257784, names the:

• package path
• package name
• build status
• platform
• compiler
• build date
• builder

But it does not name the branch that the package was built on. It would be nice if it displayed that too.
