Remove duplicate CTS tests from libcore cts packages.

The catch all "org" package was catching several thousand
org.apache.harmony.tests.* tests that are already covered by
other packages.

This change implements in CollectAllTests to handle multiple
prefixes being in passed in (separated by ':'s). This helps us
avoid creating a separate test APK for each java package.
