test/jdk/java/foreign/TestLayouts.java fails on S390X

[Vladimir Petko]

Dear Maintainers,

test/jdk/java/foreign/TestLayouts.java assumes little endian
architecture and hardcoded string representation of int.
This results in the following failure:
-----cut-----
test TestLayouts.testStructToString(): failure
java.lang.AssertionError: expected [[i4](struct)] but found [[I4](struct)]
-----cut-----
as JAVA_INT is represented as 'I4' for big endian.

Would it be possible to consider the attached patch to resolve the issue?

Best Regards,
 Vladimir.
