CHROMIUM: config: Enable CONFIG_UNICODE

After the planned migration from virtio-fs to virtio-blk for Android
/data directory (go/arcvm-virtio-blk-data), the content of Android /data
will no longer be available at /home/root/<hash>/android-data/data on
the host side.
Currently, some tast tests access the directory from the host side with
this path. In order to accommodate such tests with the virtio-blk /data
migration, we are going to mount the virtio-blk disk image of Android
/data direcory on the host side at /home/root/<hash>/android-data/data
in these tests. Since the file system for Android /data uses casefold
feature and cannot be mounted on the host without CONFIG_UNICODE, we
are enabling it on all host kernel versions that support this config.

BUG=b:233565855
TEST=Check that ARCVM guest disk image (which has casefold feature) can
TEST=be mounted on the host.
TEST=Run `chromeos/scripts/kernelconfig checkconfig`.
