build: BUILD_MISSING_DEPS - fix minor configuration options (#4493)

Address a few small issues encountered during CMake configuration step
and during build using Makefile `BUILD_MISSING_DEPS` option enabled.
- Mismatch between expected libraw versions specified in
`build_libraw.bash` 0.21.3 and `externalpackages.cmake` 0.20.0
- OpenEXR link error in libutil tests
- Update top level Makefile to accept `BUILD_MISSING_DEPS` as string
instead of bool. Pass the string option down to CMake

Verified build completes with no errors: `BUILD_MISSING_DEPS=all make`
