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: 7fdc03a737 ("tools/arch/x86: intel_sdsi: Add support for reading meter certificates")
