[baobab] dist the internal header files

[Ryan Lortie <ryanl src gnome org>]

commit 463dee7890284a02d15cecd025be25d26021b583

    dist the internal header files
    
    Include baobab-chart.h, baobab-treemap.h, baobab-ringschart.h in
    noinst_HEADERS so that they get included in the tarball.
    
    We can't put them in baobab_SOURCES because apparently automake's Vala
    support doesn't like that...
