Close #12230: Mac OS X Tiger (10.4) has a kernel bug: sometimes, the file
descriptor of a pipe closed in the parent process is valid in the child process
according to fstat(), but the mode of the file descriptor is invalid, and read
or write raise an error.
Add also requires_mac_ver() decorator to test.support.
