vendor/atf: import atf-0.24-rc1vendor/atf/atf-0.24-rc1

This release candidate will likely serve as the actual upstream
release tag for version 0.24, but for now it should be considered a
release-candidate worthy tag as this code has not gone through a full
FreeBSD test suite run or been built with `make tinderbox` yet on all
supported architectures.
