Add test for limit on intermediate certificates
Inspired by test code provided by Nicholas Wilson in PR #351.
The test will fail if someone sets MAX_INTERMEDIATE_CA to a value larger than
18 (default is 8), which is hopefully unlikely and can easily be fixed by
running long.sh again with a larger value if it ever happens.
Current behaviour is suboptimal as flags are not set, but currently the goal
is only to document/test existing behaviour.
