tests: mark as passing with SANITIZE=leak

["Rubén Justo" <rjusto@gmail.com>]

The goal in this series is to pass t3200 with SANITIZE=leak.

As a result of the fixes, other tests also pass.

This is the list of tests that no longer trigger any leak after this
series:

   + t1507-rev-parse-upstream.sh
   + t1508-at-combinations.sh
   + t1514-rev-parse-push.sh
   + t2027-checkout-track.sh
   + t3200-branch.sh
   + t3204-branch-name-interpretation.sh
   + t5404-tracking-branches.sh
   + t5517-push-mirror.sh
   + t5525-fetch-tagopt.sh
   + t6040-tracking-info.sh
   + t7508-status.sh

Each of the commits (except 11/11) fixes a leak.  They have no
dependencies on each other.  As a result, they can be reordered.

To review one leak, the commit can be moved to the tip or reverted.
E.g. to review: "branch: fix a leak in check_tracking_branch", this can
be used:

  $ git revert --no-edit HEAD~3
  $ make SANITIZE=leak test T=t3200-branch.sh 

Also, each commit have a minimal script in the message that can be used
to reproduce the leak.
