Add PUFFS_KFLAG_NOFLUSH_META to prevent sending metadata flush to FUSE

FUSE filesystems do not expect to get metadata updates for [amc]time
and size, they updates the value on their own after operations.

The PUFFS PUFFS_KFLAG_NOFLUSH_META option prevents regular metadata cache
flushes to the filesystem , and libperfuse uses it to match Linux FUSE
behavior.

While there, fix a bug in SETATTR: do not update kernel metadata cache
from SETATTR reply when the request is asynchronous, as we do not have
the reply yet.

Update file size after write without metadata flush
If we do not use metadata flush, we must make sure the size is updated
in the filesystem after a write, otherwise the next GETATTR will get us
a stale value and the file will be truncated.
