vndk-def: Exclude vndk-sp/vndk from ndk-indirect

This commit excludes VNDK-SP and VNDK libs from LL-NDK-INDIRECT and
SP-NDK-INDIRECT libs because in the degenerated VNDK design, FWK-ONLY
libs and VNDK libs share the same file.

Bug: 37867089
Test: All eligible VNDK libs are not tagged with LL-NDK-Indirect and
SP-NDK-Indirect with sailfish image.
