Revert "Revert "Remove legacy-test and legacy-android-test targets""

Fixes up the android.test.legacy target to stop using sources directly
now that the issue with android.test.runner-minus-junit not being able
to be built against the SDK has been resolved.

Also, fixes a couple of comments.

This reverts commit 7d7af10.

Reason for revert: When this was originally applied it broke the
pi-dev-plus-aosp branch as it contained references to these targets.
Those references have now been removed.

-# This builds directly from the source rather than simply statically

-# android.test.runner-minus-junit libraries because the latter library
-# cannot itself be built against the SDK. That is because it uses on

-# That class is provided by both the android.test.base-minus-junit and
-# the current SDK and as the latter is first on the classpath its
-# version is used. Unfortunately, it does not provide the internal
-# method and so compilation fails.
-#
-# Building from source avoids that because the compiler will use the
-# source version of AndroidTestCase instead of the one from the current
-# SDK.
-#
-# The use of the internal method does not prevent this from being
