Exlude mime4j depedencies via sword2, as they win out over the correct versions

[PaulBoon]

What this PR does / why we need it:

Previous PATCH-2 on v5.11.1-DANS-DataStation.

Resolves: IQSS#9077
sword2-server library overrides tika's apache-mime4j-core dependency with older version IQSS#9077

You can compare that patch 2 with patch 1:
v5.11.1-DANS-DataStation-PATCH-1...v5.11.1-DANS-DataStation-PATCH-2

Difference can be seen in pom.xml (line 90)
