[Support] Use O_CLOEXEC only when declared
Summary:
Use the O_CLOEXEC flag only when it is available. Some old systems (e.g.
SLES10) do not support this flag. POSIX explicitly guarantees that this
flag can be checked for using #if, so there is no need for a CMake
check.
In case O_CLOEXEC is not supported, fall back to fcntl(FD_CLOEXEC)
instead.
