Make xmethods tests not to depend on inferior IO.

gdb/testsuite/

	PR gdb/17017
	* gdb.python/py-xmethods.cc: Add global function call counters and
	increment them in their respective functions.  Remove "cout"
	statements.
	* gdb.python/py-xmethods.exp: Make tests check the global function
	call counters instead of depending on inferior IO.
