->capable keeps track of what capabilities kernel supports and ->wants keep
track of what capabilities filesytem wants.
Right now these fields are 32bit in size. But now fuse has run out of
bits and capabilities can now have bit number which are higher than 31.
That means 32 bit fields are not suffcient anymore. Increase size to 64
bit so that we can add newer capabilities and still be able to use existing
code to check and set the capabilities.
