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
