local file
It's a good practise to use local keyword and lower case the name of the
variable for variables used only locally (if you treat $EFIVARFS as constant,
I'd move it outside of get_secureboot_mode()).
I personally try to avoid using global variables (except constant like).

There could be helper function printing error and exit in selftest library.

Another candidate for helper for potential selftest library.
Kind regards,
