Subject: [PATCH] options: fix broken -T option

commit:
  - 175e47711c72 lib/tpm2_options: restore TCTI configuration environment variables

Broke the option handling, effectively ignoring the -T/--tcti input. Honor that input
if specified and don't just run the default TCTI search unless it's not specified.
