Fix ArgumentParserTest.test_argv_from_args to be more portable.
Fix ArgumentParserTest.test_argv_from_args to be more portable.

One of the tests was testing --jobs 4, but on a machine w/
4 CPUs, that would get reduced to the default. This patch
changes things to test --jobs 3, which is less likely to be
seen in the wild.
