[8/8] vcomp/tests: Add additional tests for _vcomp_fork.

[Sebastian Lackner]

From: Dan Kegel <dank at kegel.com>

Changes:
* The number of threads is now set to 4 before running the tests.
* Some functions were renamed.
* All fork tests are now in a single test_*() function.
* Various ok(...) messages were improved.
