The following change imports google/capsicum-test@9333154 from GitHub.
This test suite helps verify capsicum(3) support via functional tests
written in the GoogleTest test framework.
Kernel support for capsicum(4) is tested by side-effect of testing
capsicum(3).
NB: as discussed in a previous [closed] PR [1], the casper(3) tests are
incomplete/buggy and will not pass on FreeBSD. Thus, I have no intention of
integrating them into the build/test on FreeBSD as-is.
The import command used was:
```
curl -L https://github.com/google/capsicum-test/tarball/9333154 | tar --strip-components=1 -xvzf - -C dist/
```
