[gtk/issue-2: 3/7] build: Rename 'with-included-immodules' option

[Emmanuele Bassi <ebassi src gnome org>]

commit 5996b5ad6b8170d5b78352f2a3519f5c4ababc3b

    build: Rename 'with-included-immodules' option
    
    We can call it 'included-immodules', and simplify its logic by always
    attempting to split the value, to avoid turning an array into a string
    and then back into an array again.
