fs/tar: only store numeric uid/gid
If a target user is asigned a UID (e.g. 1000) that happens to also exist on the build machine, tar will happily store the username for that user. This can be seen by some as potential information disclosure. Instruct tar to just store the numeric uid/gid. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
