[RFA/MI testsuite] add expect_out global

[Keith Seitz <keiths@redhat.com>]

Hi,

The following simple patches will allow callers of mi_gdb_test to access 
the variable expect_out. Without this, expect_out will only be accessible 
in mi_gdb_test, which does test writers little good.

        * lib/mi-support.exp (mi_gdb_test): Add global declaration
        for expect_out, which will enable callers to access it.
