Rework .travis.yml to increase speed, especially for OpenCL

New advanced options OPENMM_BUILD_CPU_TESTS, OPENMM_BUILD_SERIALIZATION_TESTS,
OPENMM_BUILD_REFERENCE_TESTS were added to the cmake configuration and disabled
in the OpenCL test matrix element to increase speed. Redundant or unnecessary
apt packages removed from the travis installation.
