    mesa: fix mesa_populate_packages() when dri is disabled
    
    When compiling mesa, if dri is disabled in PACKAGECONFIG, or if the list of DRI
    drivers is empty, it will cause populate_package to fail, because it can't find
    - rightfully - the directory for the DRI drivers.  This patch checks that the
    directory indeed exists before trying to get a list of the files in it
    
    [ use oe.path.join instead of + - RB ]
