Original commit message:

  deps: limit regress/regress-crbug-514081 v8 test

  regress/regress-crbug-514081 allocates a 2G block of memory
  and if there  are multiple variants running at the
  same time this can lead to crashes, OOM kills or
  the OS failing to allocate memory.  This patch
  limits us to running a single variant of the test
