Subject: tests: avoid a false failure on OpenIndiana 11

* tests/misc/timeout-parameters.sh: Split the large timeout
handling to ...
* tests/misc/timeout-large-parameters.sh: ... here, so that
the 3 second delay is contained in its own test, and if
the test is skipped due invalid handling within timeout(1),
it will be more apparent.
Also adjust the check so we skip whenever the kernel timer
fires immediately, to handle the buggy OpenIndiana 11 kernel also.
Reported by Bruno Haible.
