backend: refactor get_custom_target_provided_libraries
the problem here is, that get_custom_target_provided_libraries iterated
over all generated sources of a target. In each output we check if this
is a library or not. In projects like EFL we have added a lot of
generated target to many different targets, so the iterating of the
output is rather consistent, with this commit we drop from 19% of the
time spending in get_custom_target_provided_libraries down to 3.51%.
