Remove com.android.bouncycastle.... classes from light grey list

Removes all the com.android.bouncycastle.... classes from the light grey
lists as they are now using UnsupportedAppUsage annotation.

This was tested by making and then manually checking that the generated
out/target/common/obj/PACKAGING/hiddenapi-light-greylist.txt was the
same (after sorting) before and after this change.

Test: see above
