[PATCH 1/1] efi_loader: sanitize efi_tcg2_final_events_table definition

[Heinrich Schuchardt]

The length of the variable name typically is not 1.
Neither the length of the variable name nor the size of the appended
data is known in the include.

* Define the size of element variable_name as variable.
* Remove the unusable element variable_data.
