before this change, we used the lower-case CMake build configuration
name for the rust profile names. but this was wrong, because the
profiles are named with the scylla build mode.
in this change, we translate the $<CONFIG> to scylla build mode,
and use it for the profile name and for the output directory of
the built library.
