apparmor: Explicitly pass options we use while remounting root filesystem
As a result of AppArmor commit d4b0fef10a4a ("parser: fix rule flag generation change_mount type rules"), we can't expect anymore to get permission to mount() / read-write, with MS_REC | MS_UNBINDABLE ("runbindable", in AppArmor terms), if we don't explicitly pass those flags as options. It used to work by mistake. Now, the reasonable expectation would be that we could just change the existing rule into: mount options=(rw, runbindable) "" -> /, ...but this now fails to load too, I think as a result of AppArmor commit 9d3f8c6cc05d ("parser: fix parsing of source as mount point for propagation type flags"). It works with 'rw' alone, but 'runbindable' is indeed a propagation type flag. Skip the source specification, it doesn't add anything meaningful to the rule anyway.
