bisect.jpl: force-fetch git tags

Run "git fetch --tags -f" to force updating tags if there was already
one with the same name as an incoming one.  This caused some
bisections on clk/clk-next to fail with this error:

  ! [rejected]                  clk-for-linus       -> clk-for-linus  (would clobber existing tag)

This issue didn't occur with earlier versions of git (tested with
2.11.0) but can be reproduced with the version in the
kernelci/build-base docker image (2.19.2).  With the "-f" flag, the
[rejected] message is replaced by a [tag update] like in earlier git
versions and the new tag replaces the older one.
