    selftests: ve_printk: match the conntrack overflow message
    
    The kernel prints
    
      VE%s: nf_conntrack table full in netns %u, dropping packet
    
    while the test looks for "nf_conntrack table full, dropping packet".
    The "in netns %u" part sits between the two halves the test expects to
    be adjacent, so strstr() never matched: ve_log_both counted zero
    messages and failed even when the container produced all ten of them.
    
    Match the part of the message which carries no netns number, and drop
    the stale quote from the comment above the test.
