efi_selftest: allow to select a single test for execution
Environment variable efi_selftest is passed as load options
to the selftest application. It is used to select a single
test to be executed.
The load options are an UTF8 string. Yet I decided to keep
the name propertiy of the tests as char[] to reduce code
size.
Special value 'list' displays a list of all available tests.
Tests get an on_request property. If this property is set
the tests are only executed if explicitly requested.
The invocation of efi_selftest is changed to reflect that
bootefi selftest with efi_selftest = 'list' will call the
Exit bootservice.
