Subject: [PATCH v4 2/2] test: simplify spawning extra test processes

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, by using argv[0] as the binary to run, rather than
querying procfs for /proc/self/exe (or /proc/curproc/file on FreeBSD).
The unit tests should never be running in a way that leads to argv[0]
not being the actual test binary.
