Add ACLs to java SimpleService so examples run when SECURED=1

Add ACLs to java SimpleService so examples run when SECURED=1

The ModeType in SimpleClient is changed to CLIENT_SERVER
This is a work around for IOT-693

the ioc_svr_db_server ACL file is a copy of the ACL file from
resource/examples.

The example will run against the simpleservice simpleclient in
resource.

Build:
scons BUILD_JAVA=1

Run examples:
export LD_LIBRARY_PATH=<iotivity>/out/linux/x86_64/release/

java -cp java/examples-java/simpleserver/build/libs/simpleserver.jar:\
java/iotivity-linux/build/libs/iotivity-linux.jar \
org.iotivity.base.examples.SimpleServer

java -cp java/examples-java/simpleclient/build/libs/simpleclient.jar:\
java/iotivity-linux/build/libiotivity-linux.jar \
org.iotivity.base.examples.SimpleClient
