[Rpm-maint] [rpm-software-management/rpm] Use close_range() to set close-on-exec on all fds (PR #4149)

[Panu Matilainen]

@pmatilai requested changes on this pull request.

This is failing to build in CI because of this warning:
> :1791:13: error: unused function 'set_cloexec' [-Werror,-Wunused-function]
1.164  1791 | static void set_cloexec(int fd)

Probably easiest to just ifdef the whole rpmSetCloseOnExec() implementation: the new variant just calls close_range() and the other branch includes the existing loop and the helper function.
