tools/arch/x86/intel_sdsi: Fix meter_show display

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: 7fdc03a7 ("tools/arch/x86: intel_sdsi: Add support for reading meter certificates")
