When allocating disk space, for Linux system with fallocate()
system call, first check file system supports fallocate. This
just run fallocate with small chunk and see it succeeds or fails.
If it succeeds, use fallocate() to allocate entire file otherwise
fall back to traditional slower method: writing zeros. This
behavior is enabled in --file-allocation=prealloc, so this is
enabled by default for most modern Linux.
