Gnulib's get_fs_usage() (which is what GNU coreutil's df uses)
does not handle EINTR either.

There is some code that does int width expansion, but I believe we
don't need that since the `fst.f_bavail * fst.f_frsize` multiplication
takes care of converting that to int64 (if it wasn't already 64bits
before).
