file: let dup_fd() drop only close-on-exec descriptors
Add FD_RANGE_CLOEXEC_ONLY. When set dup_fd() leaves everything behind
except for fds that are close-on-exec. Without FD_RANGE_EXCEPT the
clone loses the close-on-exec descriptors in the range. With it the
clone keeps the range and loses the close-on-exec descriptors everywhere
else. Descriptors without the flag are carried over either way.
Nothing passes the flag yet.
