executor: fix up /dev/net/tun before opening it
We get various reports like: "SYZFAIL: tun: can't open /dev/net/tun":
https://syzkaller.appspot.com/bug?extid=17b76f12c4893fc7b67b
or like "SYZFAIL: tun: ioctl(TUNSETIFF) failed"
https://syzkaller.appspot.com/bug?extid=49461b4cd5aa62f553fc
Which look a lot like syzkaller manages to delete or replace
/dev/net/tun and from there on consistently fail to open the device and
complains with these SYZFAIL.
This is an attempt to fix up the /dev/net/tun before we open it so we
know we try to open the right file.
