selftests/filesystems/overlayfs: fix set_layers_via_fds link error
set_layers_via_fds.c calls open_tree() directly, but that wrapper is
not provided by all C libraries, so the test fails to link with
"undefined reference to open_tree" on toolchains without it.
Use sys_open_tree() from ../wrappers.h, the syscall wrapper already
used for move_mount(), fsmount() and friends here. This is also a
prerequisite for building the new idmapped_mounts test added to this
directory.
