[PATCH v2 2/2] test: simplify spawning extra test processes

[Bruce Richardson <bruce.richardson@intel.com>]

A number of tests require secondary processes or additional primary
process instances, so we have common code for managing that in the test
binary. Simplify that code a little, in the process removing dependency
on procfs on FreeBSD
