[RFA] Fix mi-var-child-f.exp failures

[Keith Seitz <keiths at redhat dot com>]

Hi,

This test file contains three "new" failures which are actually not 
failures. They've been failing ever since dynamic varobjs went in:

commit 8e8a4e3d9ea92ce53f8d5373b1b8865c9c92636b
Author: Tom Tromey <tromey@redhat.com>
Date:   Tue Sep 15 18:51:24 2009 +0000

As a result of this commit, MI will now output a "has_more" attribute to 
-var-create, -var-update, and -var-list-children. The commit caught most 
of the places in the test suite where this needed to be added, but not 
many of us appear to have a fortran compiler installed, so 
mi-var-child-f.exp was overlooked.

I've chosen to fix as much of these tests by using standard test 
procedures (mi_create_varobj and mi_list_varobj_children) when possible.

Ok?
Keith

	* gdb.mi/mi-var-child-f.exp: Use mi_create_varobj.
	Use mi_list_varobj_children for the immediate children of `array'.
	Add "has_more" attribute for grandchildren test.
