    tools/arch/x86/intel_sdsi: Fix meter_show display
    
    [ Upstream commit 76f2bc17428c890754d11aa6aea14b332ba130c5 ]
    
    Fixes sdsi_meter_cert_show() to correctly decode and display the meter
    certificate output. Adds and displays a missing version field, displays the
    ASCII name of the signature, and fixes the print alignment.
    
    Fixes: 7fdc03a7370f ("tools/arch/x86: intel_sdsi: Add support for reading meter certificates")
