ipv6: ip6_gre: replace strcpy with strscpy for tunnel name
Replace the strcpy() call that copies the device name into
tunnel->parms.name with strscpy(), to avoid potential overflow
and guarantee NULL termination. This uses the two-argument
form of strscpy(), where the destination size is inferred
from the array type.
Destination is tunnel->parms.name (size IFNAMSIZ).
Tested in QEMU (Alpine rootfs):
- Created IPv6 GRE tunnels over loopback
- Assigned overlay IPv6 addresses
- Verified bidirectional ping through the tunnel
- Changed tunnel parameters at runtime (`ip -6 tunnel change`)
