Update to 1.09

Upstream changes:
1.09 2018-09-26 NEILB
    - Only one odd looking fail on CPAN Testers, so doing a non-developer
      release, as that will get more testing.

1.08_05 2018-09-26 NEILB
    - After lots of testing to try and cope with parallel smoke testers,
      decided its best to avoid that problem by having each installation
      create a unique name for the pidfile, so the tests won't collide.

1.08_04 2018-09-24 NEILB
    - Don't bother with /var/run
    - Use File::Spec to portably build paths. Hopefully will sort out
      at least some of the Windows fails on CPAN Testers.

1.08_03 2018-09-16 NEILB
    - I realised that some of the test cases should set the new "retries"
      parameter to zero, otherwise they'll increase the chance of problems
      with parallel smokers.

1.08_02 2018-09-13 NEILB
    - Extended the SEE ALSO section with a bunch of modules for the same task.
    - Changed the parameter name from "attempts" to "retries",
      and added documentation for it.
    - Added verbose message about backing off.

1.08_01 2018-09-12 NEILB
    - If pidfile already exists and process is running,
      retry a couple of times. Parallel smoke testers were producing
      spurious fails; this will hopefully fix that, and is potentially
      a useful feature to have anyway.

1.08 2018-09-07 NEILB
    - Fixes for when running in taint mode. One fix from Laurence Darby,
      and one from me.
    - Include META.json in releases
    - Made the SEE ALSO mention of Proc::PID::File linked -- MANWAR.

1.07_01 2018-09-07 NEILB
    - Fixes for when running in taint mode. One fix from Laurence Darby,
      and one from me.
    - Include META.json in releases
