make the checkok test stricter to avoid races, and use O_REGULAR.
Instead of opening the file and using popen(3), pass the file descriptor
to sendmail directory. Idea and code from Todd Miller.
Add O_REGULAR to enforce opening of only regular files
(like we have O_DIRECTORY for directories).
This is better than open(, O_NONBLOCK), fstat()+S_ISREG() because opening
devices can have side effects.
