Use $disabled{"dynamic-engine"} internally

We were kinda sorta using a mix of $disabled{"static-engine" and
$disabled{"dynamic-engine"} in Configure.  Let's avoid confusion,
choose one of them and stick to it.

      only requirement for building dynamic engines is the presence of

      This only applies to the engines in engines/, those in
      crypto/engine/ will always be built into libcrypto (i.e. "static").
