From: Bobby Eshleman <bobbyeshleman@meta.com>

Remove the namespaces upon exiting the program in cleanup().  This is
unlikely to be needed for a healthy run, but it is useful for tests that
are manually killed mid-test. In that case, this patch prevents the
subsequent test run from finding stale namespaces with
already-write-once-locked vsock ns modes.
