[PATCH ima-evm-utils v2 5/9] Introduce TST_LIST variable to select a test to execute

[Roberto Sassu <roberto.sassu@xxxxxxxxxxxxxxx>]

From: Roberto Sassu <roberto.sassu@xxxxxxxxxx>

It might be desirable, due to restrictions in the testing environment, to
execute tests individually. Introduce the TST_LIST variable, which can be
set with the name of the test to execute. If the variable is set,
expect_pass and expect_fail automatically skip the tests when the first
argument of those functions does not match the value of TST_LIST.

TST_LIST can be also used in conjunction with the UML kernel. It is
sufficient to add it to the kernel command line.
