Fix MI testsuite failures for gdbserver

[Daniel Jacobowitz <drow at false dot org>]

Nathan made mi-console.exp skip the inferior I/O test if
gdb,noinferiorio was set.  Later, Bob Rossi made it use the fancy new
separate TTY support; at that point the inferior I/O check was lost.
This adds it back.

I also removed the use of puts from mi-syn-frame.exp; it's irrelevant
to the test.  Andrew suggested this to me way back in 2004.

Tested on x86_64-linux native and with gdbserver, and committed.

	* gdb.mi/mi-syn-frame.c (main, foo, bar)
	(have_a_very_merry_interrupt): Remove calls to puts.
	* gdb.mi/mi-syn-frame.exp, gdb.mi/mi2-syn-frame.exp: Do not expect
	inferior output.
	* lib/mi-support.exp (mi_gdb_test): Check gdb,noinferiorio.  Correct
	test names.
