gcov: use strscpy() instead of strcpy() in init_node()

Browse Source 
node->name is a flexible array member sized to exactly strlen(name) + 1
bytes at allocation time in new_node(), so this copy can never actually
overflow.  Still, prefer the bounded strscpy() over strcpy() on general
principle; pass the same strlen(name) + 1 bound the allocation used, since
sizeof() cannot be applied to a flexible array member.

No functional change.
