These were previously reporting leaks due to various allocations not
getting cleaned up during the stack unwind, but at the current state of
the transition toward IntrusivePtr usage, theses tests no longer leak.
* Generally increase timeouts for tests that have recent transient
failures
* Change any test that relied on `btest-bg-wait -k` since that's never
going to play with with CI systems. Instead, we always need to have
a well-defined termination condition in the test itself (and most
already did, so didn't really need the `-k` flag anyway).
E.g. ones that throw interpreter exceptions, as those are currently
known to potentially cause leaks. Fixing the underlying leaks involves
the larger task of more IntrusivePtr usage.
Reference cycles may also cause leaks.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
