MutualTlsTest.mTls() fails on Quarkus Platform

[ppalaga]

... because we have local paths in application.properties

quarkus.cxf.client.mTls.key-store = target/classes/client-keystore.${keystore.type}
quarkus.cxf.client.mTls.trust-store = target/classes/client-truststore.${keystore.type}

but we do not extract them before running the test from test jar.
