Bug 18055 - Speed up '00-strict.t' test, with Parallel::ForkManager

add KOHA_PROVE_CPUS envar to manually set number of cpus

to test..

1/ set number of cpus to 1
 $ export KOHA_PROVE_CPUS=1

2/ observe 1 cpus are used
 $ time prove -v  t/db_dependent/00-strict.t
 t/db_dependent/00-strict.t ..
 Using 1 CPUs...

3/ unset number of cpus
 $ export KOHA_PROVE_CPUS=

4/ observe all available cpus are used
 $ time prove -v  t/db_dependent/00-strict.t
 t/db_dependent/00-strict.t ..
 Using 32 CPUs...

I've added this patch

Could we use the same method for
  t/00-testcritic.t,
  t/00-merge-conflict-markers.t,
  xt/author/valid-templates.t and
  xt/author/translatable-templates.t
as well?

Any volunteers?
