    mwlwifi: use PKG_SOURCE_DATE instead of version
    
    Using PKG_SOURCE_DATE instead of PKG_VERSION will make the build system
    generate the version based on the date and the git hash. This way the
    tar file name changes when the git hash changes and this avoids problems
    when someone forgets to change the version, but changes the git hash.
