Subject: [PATCH] luks: enable debugging in clevis scripts when rd.debug is set
 (#340)

On Fedora/RHEL, the rd.debug kernel command line parameter controls
debugging.
By implementing the functionality inside clevis, troubleshooting will be
greatly eased.
See RHBZ #1980742 (https://bugzilla.redhat.com/show_bug.cgi?id=1980742).
