Remove last internal consumer of DSO
It is currently possible to extend libcrypto by having it load a shared
object via dlopen() either from a config file on library initialization
or when an application calls the relevant API. Recent and not so recent
events showed how dangerous an idea dlopen() is. Independently of such
concerns, this should not be handled in the characteristically convoluted
way of this toolkit. DSO will go away in the upcoming bump. This commit
clears the road for a plain cvs rm of the dso code.
