include CHECKSUM_TYPES in kojikamid.py, and use it when validating checksums of downloaded files

Browse source 
The Koji data model has been updated to support multiple checksum types. These are listed in the
CHECKSUM_TYPES enum in koji/__init__.py, but are not available in kojikamid.py. This change
copies the Enum class and the CHECKSUM_TYPES enum into kojikamid at build time, and uses it when
validating the checksums of downloaded files.
