support/testing/tests/core/test_selinux: new test for BR2_PACKAGE_REFPOLICY_CUSTOM_GIT
Add a test for BR2_PACKAGE_REFPOLICY_CUSTOM_GIT (which allows to select
a custom location for the SELinux refpolicy). The test uses the official
refpolicy as a test (we only want to test the functionality is working,
not that another refpolicy is correctly building; that is an user
problematic).
