Disable warnings for unsupported @SuppressWarnings annotations in Eclipse

We use a lot of @SuppressWarnings annotations for suppressing ErrorProne
issues that are not known to Eclipse. At the moment these show up as
warnings, e.g. 'Unsupported @SuppressWarnings("BanSerializableRead")'.
Since having these annotations is intended we don't need a warning for
them. Having these warnings adds a lot of noise so that other warnings,
for things we would like to address, stay unnoticed. Hence disable these
warnings.
