Revert "Support libraries (not just boot jars) that have hiddenapi"

This reverts commit e5b5657f.

The reverted change was added in order to gather the information about
the hiddenapi that is needed for the runtime to enforce the hiddenapi
accessibility rules. Without it the build broke with the following
error when the android.test.base library was not in the
PRODUCT_BOOT_JARS list:

AssertionError: Error processing: frameworks/base/config/hiddenapi-greylist.txt
The following entries were unexpected:
  Ljunit/framework/TestSuite;->isPublicTestMethod(Ljava/lang/reflect/Method;)Z
  Landroid/test/AndroidTestCase;->setTestContext(Landroid/content/Context;)V
  Landroid/test/InstrumentationTestCase;->runMethod(Ljava/lang/reflect/Method;I)V
  Landroid/test/AndroidTestCase;->getTestContext()Landroid/content/Context;
  Ljunit/framework/TestCase;->fName:Ljava/lang/String;
  Ljunit/framework/TestSuite;->isTestMethod(Ljava/lang/reflect/Method;)Z
  Please visit go/hiddenapi for more information.

However, it turns out that the runtime does not currently enforce
access to the hiddenapi of libraries that are not on the
PRODUCT_BOOT_JARS list. Gathering hiddenapi information for a library
not on the PRODUCT_BOOT_JARS list breaks the
CtsHiddenApiBlacklistApi27TestCases and
CtsHiddenApiBlacklistApi28TestCases test modules which use that
information to ensure that correct runtime behavior.

This change is being reverted simply because it does not work.
