Fix build on systems without O_CLOEXEC (re: 9f43f8d1)

Browse source 
A build failure on HP-UX B.11.11 was introduced when O_cloexec was
changed to O_CLOEXEC (which is POSIX standard) in the backported
93v- code. The lowercase variant is conditionally defined by libast
in src/lib/libast/features/fcntl.c precisely for compatibility with
systems that do not have O_CLOEXEC.

src/lib/libast/tm/tvtouch.c:
- Revert to using the AST O_cloexec flag when calling open(2).
