Fix hash function config tests with CMake

Fix hash function config tests with CMake

The commit "Improve portability of MD5/SHA* headers and functions" added
both autotools and CMake detection of MD5, RMD, and SHA* hash functions.
The commit "Move hashing function calling into a separate file" rewrote
the autotools logic and changed the source to use different config
macros but did not update the CMake logic.  This commit updates the
CMake configuration tests to produce the result macros the code expects.
