description:
t_ptm.c: add a test case that passes extra flags
Validate that O_NONBLOCK and O_CLOEXEC are actually set by
posix_openpt(3), as until circa 9.99.101 they were not.
If/when other flags are added like close-on-fork, this test could be
adjusted. The current concern is with supporting the expectations of
components like vte3, used by various graphical terminal clients.
