fuse-overlayfs: fix lookup with multiple layers

fuse-overlayfs: fix lookup with multiple layers 
when looking up multiple layers and we have already found a file, do
not check if whiteouts are present in lower layers.  The lookup in the
lower layers is needed only to correctly propagate the inode number.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1686889

fuse-overlays: fix interaction of unlink(2) with readdir(2) 
fix an interesting interaction between unlink(2) and readdir(2) that
can confuse the cache.

If a file is unlinked before the readdir(2) is done, it is not removed
from the list generated when the directory was first opened.  Thus the
result is that readdir(2) will return the file even if it was unlinked
and moved to the work dir until the cache is released.

The fix is to skip dentries that are hidden while iterating the list.

a9091e4bd8 setattr: use fd from fi->fh for ftruncate() whenever possible 
When a file is created with restricted permissions (like 000), ftruncate() should
still work as long as the fd is open. If fi->fh is available, use it to fix that
and avoid the call to openat() which failed in that case.
