Some ApparmorTestsuites test fail on focal

[Roxana Nicolescu]

The following fail on focal on exotic-skunk.amd64

ApparmorTestsuites.test_regression_testsuite
ApparmorTestsuites.test_utils_testsuite3
ApparmorTestsuites.test_parser_testsuite
ApparmorTestsuites.test_libapparmor_testsuite
ApparmorTestsuites.test_libapparmor_testsuite3

It's not a regression, they failed on previous versions as well.

Error seems similar for all of them, this is for test_regression_testsuite
