Package names omit OS/version

Hi,

Connector/ODBC packages are being generated without including the OS name and version, which means that for example we end up with a situation like this:

connector-odbc-2.0.14/jessie_x64-connector-odbc/mariadb-connector-odbc-2.0.14-ga-linux-x86_64.tar.gz

connector-odbc-2.0.14/centos7_x64-connector-odbc/mariadb-connector-odbc-2.0.14-ga-linux-x86_64.tar.gz

connector-odbc-2.0.14/centos6_x64-connector-odbc/mariadb-connector-odbc-2.0.14-ga-linux-x86_64.tar.gz

These 3 packages, built on and for different OSs, all end up with the same filename. This is confusing, but more seriously it is incompatible with the mariadb.com/downloads download infrastructure.

Please change to a package naming strategy that includes the OS name and version. This will probably require a change in CMake.
