Unit tests fail due to check_accepted_eula

[SebastianAchilles]

EasyBlocks that make use of the function check_accepted_eula (easybuilders/easybuild-framework#3535) will fail in the Unit tests, because the EULA is not accepted. This is the case for #2295

One possible solution would be to set the environment variable EASYBUILD_ACCEPT_EULA for that specific EasyBlock in the Unit test.

Another possible solution would be to include in accept_eula = True in the Dummy easyconfig file, e.g. here

easybuild-easyblocks/test/easyblocks/module.py

Line 92 in 8dcb466

'sources = []',

Another possible solution would be to skip the check_accepted_eula function for --module-only.

I think the last option is the best. This can be done very easily by moving check_accepted_eula to the install_step. In that case the check is not executed for --module-only and the Unit test is passed.
