[PATCH net-next v2] net: tipc: replace deprecated strcpy with strscpy

The `strcpy()` function is deprecated and moving towards code-tree
elimination. Replacing it with `strscpy()` fixes potential buffer
overflow vectors by ensuring safe NULL-termination based on the
destination buffer size limit [1][2].

In `tipc_bearer_get_name()`, the 'name' parameter decays into a pointer,
meaning `sizeof()` cannot capture the underlying array bounds directly.
However, all parent callers allocate this buffer using the
TIPC_MAX_BEARER_NAME macro.

Replace strcpy() with strscpy() using TIPC_MAX_BEARER_NAME as the
explicit destination bound length.
