Christian Brauner f2c09fa04c fs: support O_PATH fds with FSCONFIG_SET_FD

[ Upstream commit 0ff053b98a ]

Let FSCONFIG_SET_FD handle O_PATH file descriptors. This is particularly
useful in the context of overlayfs where layers can be specified via
file descriptors instead of paths. But userspace must currently use
non-O_PATH file desriptors which is often pointless especially if
the file descriptors have been created via open_tree(OPEN_TREE_CLONE).
