Fix javapackager failing testcases mentioned in description of bug

1. Remove dot while passing value to -name and replace with underscore operator.
i.e. Change -name JvmOptionsTest_CLI_NormalJar_linux.app to -name JvmOptionsTest_CLI_NormalJar_linux_app, it's a workaround for https://bugs.openjdk.java.net/browse/JDK-8170697

2. Fix failing test case com.oracle.appbundlers.tests.functionality.SecondLauncherSameJreTest, this is also fix for https://bugs.openjdk.java.net/browse/INTJDK-7616958
3. Fix failing test case com.oracle.appbundlers.tests.functionality.SecondLauncherWithJvmParametersTest
4. Fix failing test case com.oracle.appbundlers.tests.functionality.CoupleSecondaryLaunchersTest
