[jhbuild] environment: set OBJC_INCLUDE_PATH

    environment: set OBJC_INCLUDE_PATH
    
    Some libraries (GLib and Gtk, for example) compile some files using the
    objective C compiler on Mac OS.  This compiler won't find headers in
    paths in C_INCLUDE_PATH; it needs them in OBJC_INCLUDE_PATH.
