Ensure no redundant ABI reference dumps

This commit ensures that all ABI dumps under prebuilts/abi-dumps/ have
corresponding NDK/VNDK libraries. When an NDK/VNDK library is removed
but its ABI dump isn't, the build system reports an error.

The build system does not check whether all NDK/VNDK libraries have ABI
reference dumps because the owners of the libraries may intend to
disable ABI check in some cases.

Test: touch prebuilts/abi-dumps/vndk/R/32/x86/test.so.lsdump && make
