    core-deps/tracker.bst: Fix installation directory for bash completions
    
    This was being installed in /share, because ${prefix} is an environment
    variable (that is not set), it should have been expanding the %{prefix}
    variable, but now using just  %{datadir} for /usr/share as it's more
    appropriate.
