ci: Use a RAM disk and more CPUs on FreeBSD. Run the tests in a RAM disk. It's still a UFS file system and is backed by 20GB of disk, but this avoids a lot of I/O. Even though we disable fsync, our tests do a lot of directory manipulations, some of which force file system meta-data to disk and flush slow device write caches on UFS. This was a bottleneck preventing effective scaling beyond 2 CPUs.
Now we can use 4 CPUs like on other OSes, for a huge speedup.
