kernel32/tests: check return value of alarmThread in test_NamedPipe_2() (try 2)

[Austin English]

Changes from try 1:
Fix another typo.
Set LastError before checking it
Print LastError as a decimal
Don't check for INVALID_HANDLE_VALUE as a return value of
CreateThread, instead make sure serverThread is not NULL.
