POSIX::dup2 does not do anything in addition to dup2(2) and is thus immune to Perl automatically setting FD_CLOEXEC on FDs it makes into IO objects/globs. We only need to account for the case when both args for dup2 are identical, in which case the kernel treats it as a no-op and then thus we need to clear FD_CLOEXEC ourselves.
