[PATCH 2/2] test-lib: ulimit does not limit on CYGWIN and MINGW

[Michael J Gruber <git@grubix.eu>]

ulimit succeeds (by return value) but does not limit on some systems.

Set ulimit() to false on these systems so that we do not rely on its
output nor effect. As an intended side-effect, ulimit based
prerequisites are set correctly (to "not-have") on these systems.

This is independent of my series, but should best go before so that no
ulimit based test is run on CYGWIN and MINGW.

It follows the basic assumption that a tool like ulimit is either
present and functional or not present; and that we work around by
defines or such when that assumption is broken.
(Alternatively, we could set ULIMT_LIMITS or so and depend on that.)
