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.

Closes: https://github.com/containers/libpod/issues/2342

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.
