fuse: add FUSE_NO_OPEN_SUPPORT flag to INIT
Here some additional changes to set a capability flag so that clients can
detect when it's appropriate to return -ENOSYS from open.
This amends the following commit introduced in 3.14:
7678ac50615d fuse: support clients that don't implement 'open'
However we can only add the flag to 3.15 and later since there was no
protocol version update in 3.14.
