Remove temporary filtering of ICU output on host

This commit undoes changes Ibe27047549fd7c3c556e2e754015a2cfaa97d6cf
and Ib6c0e55d0c6fcc932999428f21c51afe32ab7ef2. The ICU logging code on
host now respects ANDROID_LOG_TAGS. ART run tests explicitly set the
log level so ICU initialization messages are suppressed once again and
no longer appear in the test output and break expectations.

Fix: 171770326
Test: art/test/run-test --host 001-HelloWorld
Test: art/test.py --host -r --64 --optimizing
