Disable CtsLibcoreJavaUtilCollectionsTestCases.

This module is flaky due to what looks like a bug in the test infrastructure.
The code under test by this module is very rarely modified by vendors, so
the presence of additional test coverage (vs. less comprehensive libcore tests)
in CTS is not critical.

This CL disables the entire module by default until we find a longer
term solution.
