Ronald G. Minnich 67399c6279 syscall: fix ordering of Unshare and chroot on Linux
When unshare specifies a new namespace, the syscall
package changes / to make namespace changes private.

If a chroot is specified, the unshare must be done first.
If the chroot is done first then the unshare will
not specify the correct /.

A new test is included which test combining chroot
and CLONE_NEWNS; it fails without the patch and works with
it.

Fixes #20103
