Use mi_varobj_update in mi-var-child.exp and mi2-var-child.exp

I modify mi-var-child.exp and find that the pattern to match the output
of -var-update * is quite complicated. However, it can be simplified by
using mi_varobj_update. That is what this patch does.

* gdb.mi/mi-var-child.exp: Use mi_varobj_update to simplify
tests.
* gdb.mi/mi2-var-child.exp: Likewise.
