remote: Fix bogus make_branch() call in configuration reader.

The configuration reader to enumerate branches that have configuration
data were not careful enough and failed to skip "branch.<variable>"
entries (e.g. branch.autosetupmerge).  This resulted in bogus attempt to
allocate huge memory.

Noticed by David Miller.
