gdb.base/async.exp: Handle "asynchronous execution not supported"

This change eliminates some failures on simulator targets and makes
the test run a bit quicker too - without this change, we have to wait
for timeouts.

gdb/testsuite/ChangeLog:

	* gdb.base/async.exp (proc test_background): Add case
	for asynchronous execution not supported.
