[PATCH net-next] ipv4: ip_tunnel: Replace strcpy use with strscpy

[Ruben Wauters <rubenru09@aol.com>]

Use of strcpy is decpreated, replaces the use of strcpy with strscpy as
recommended.

I am aware there is an explicit bounds check above, however using
strscpy protects against buffer overflows in any future code, and there
is no good reason I can see to not use it.
