Disable binder caches for unit tests

Bug: 152451909

Disable binder caches for the following tests:
 * PackageManagerSettingsTests
 * UserManagerServiceCreateProfileTest
 * UserManagerServiceIdRecyclingTest
 * UserManagerServiceUserInfoTest

Test: run the above tests and verify no failures related
to system property privileges.  All tests pass except for
the first one.  In PackageManagerSettingsTests, two of
the 18 tests fail for reasons unrelated to binder caches.
Ran all the tests in frameworks/base/services/tests/
servicestests/src/com/android/server/pm.  Only a few
failures were seen but no SELinux issues.
