Revert "Merge commit '61c31e4e'" (configure: Properly set zlib dependencies for all components)

The reverted commit introduced undefined behavior.
undefined in the sense that the evaluation order of the dependencies affects the results

Fixes Ticket2920

This reverts commit c32db6ad, reversing
changes made to 05f1b4e2.

Alternative solutions would be to change the dependency solver to handle non trivial
dependencies or to enable zlib by default before the dependency solver, this would
leave a zlib dependency in the libs though then even when no zlib is needed or used.

Before this commit, sws_init_context() failed with an error if no scaler
was explicitly set.

Defaulting to something reasonable is better behavior.

That's the more proper place where the scaler options should be
documented.
