Fix ioctl(2) code for OpenBSD ( #1175 )
...
This cleans up the mess to configure an IP address on a tun(4) device.
Handrolling a hardcoded ioctl(2) request is far from perfect, but Go
(golang.org/sys/unix) is to blame here.
Tested on OpenBSD 7.6 -current where yggdrasil now drives the interface
would use of ifconfig or other helpers.

tun: bsd: remove redundant ioctl to set MTU ( #1172 )
...
wireguard's CreateTUN() sets the MTU using the same ioctl(2), on both
FreeBSD and OpenBSD.
Tested on OpenBSD (outputwith this patch):
```
# ktrace ./yggdrasil -autoconf | grep Interface
2024/09/24 17:26:29 Interface name: tun0
2024/09/24 17:26:29 Interface IPv6: 201:26e:68f0:502e:f445:13eb:2fe1:f7cd/7
2024/09/24 17:26:29 Interface MTU: 16384
```
```
$ ifconfig tun0 | head -n1
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 16384
```
```
# kdump | grep ioctl
53097 yggdrasil CALL ioctl(10,SIOCGIFMTU,0xc0000376b8)
53097 yggdrasil RET ioctl 0
53097 yggdrasil CALL ioctl(10,SIOCSIFMTU,0xc0000376c0)
53097 yggdrasil RET ioctl 0
53097 yggdrasil CALL ioctl(10,SIOCGIFMTU,0xc0000377f8)
53097 yggdrasil RET ioctl 0
53097 yggdrasil CALL ioctl(10,_IOW('i',12,0x20),0xc00003777c)
53097 yggdrasil RET ioctl -1 errno 25 Inappropriate ioctl for device
"2024/09/24 17:26:29 Error in SIOCSIFADDR_IN6: inappropriate ioctl for device
```
(The completely broken address ioctl is another story...)

Remove waitForTUNUp from TUN

Fixed wait for TUN to come up ( #1157 )
...
So, the function waiting for TUN to come up never succeeds:
```
func waitForTUNUp(ch <-chan wgtun.Event) bool {
t := time.After(time.Second * 5)
for {
select {
case ev := <-ch:
if ev == wgtun.EventUp {
return true
}
case <-t:
return false
}
}
}
```
I've tried the sleep for one second, and it works flawlessly on several
PCs.
Another point - sometimes, if the service stop abruptly (in case of some
errors) there is an old hidden device in the system, that we need to
uninstall, and then create new.

TUN vectorised reads/writes ( #1145 )
...
This PR updates the Wireguard dependency and updates to use new
vectorised reads/writes, which should reduce the number of syscalls and
improve performance.
This will only make a difference on Linux as this is the only platform
for which the Wireguard TUN library supports vectorised reads/writes.
For other platforms, single reads and writes will be performed as usual.
