As statfs.f_flags are uint64_t the local variables should be as well.

We'll start noticing this with the next flag introduced as the lower
32bit are all used.
As this is old code we might need to do a full tree sweep one day, unless
changing our strategy to use a different `API' for getting/setting flags
along with the rest of the statfs data.

While here compare to 0 explicitly [1].
