refactor(fossil): use `fossil branch current` supported since v2.7 (#11138)

Using the automation-friendly "fossil branch current" feature added in Fossil 2.7 instead of ad hoc parsing of human-readable "fossil branch" output. Not only does this fix a stray space in the output, it's more robust against changes in command output in general. Closes #11138
