owner: Fix potential array out of bounds access

If the link target length exceeds 'sizeof(tmp)' bytes, readlink() will
return 'sizeof(tmp)'. Using this value as index is illegal.

Original update from Phil, for the conntrack-tools tree, which also has
a copy of this function.

Fixes: 6d085b22a8b5 ("table: support for the table owner flag")
