    jhbuild build: suggest passing the active module list to systeps --install
    
    In case of "build foo" and foo requires a missing sysdep we currently suggest
    running "sysdeps --install" which will install all sysdeps, not just the ones
    needed to make "build foo" work.
    
    Instead suggest running "sysdeps --install foo" to only install the required sysdeps.
    
    Fixes #45
