[gegl] Remove dt:exposure

[Debarshi Ray <debarshir src gnome org>]

commit 09950e1342a766bd6abb68cac3a0241060d3a5b0
Author: Debarshi Ray <debarshir gnome org>

    Remove dt:exposure
    
    This no longer so useful because gegl:exposure now has the same 'black'
    property, and has more features. Exposure adjustment in sRGB doesn't
    make sense, so that doesn't count.
