vndk: remove hidl vndk-sp libs from the list.

With BOARD_VNDK_VERSION:=current, vndk-sp libs will be installed to
/system/lib(64)/vndk-sp directory with
'vndk: {enabled: true, support_system_process: true}' property in
Android.bp of the module.

Remove the modules that already has the 'vndk' property in their
Android.bp file in case BOARD_VNDK_VERSION is defined.

Bug: 63866913
Test: build and boot with and without OARD_VNDK_VERSION=current
