Fix check_elf_file with LOCAL_SDK_VERSION and NDK libs

This commit fixes prebuilt ELF checker for modules with
LOCAL_SDK_VERSIONS and depend on NDK shared libraries. This fix is
required because dynamic_binary.mk filters out NDK libraries thus those
libraries do not show up in DEPENDENCIES_ON_SHARED_LIBRARIES.

Bug: 119084334
Test: Create a prebuilt module with LOCAL_SDK_VERSION and check whether
      the NDK libs in LOCAL_SHARED_LIBRARIES are passed to
      check_elf_file.py.
