fix: GCC 15 raised -Wincompatible-pointer-types

Browse source 
On GCC 15.1.0, the error
sysfs.c:47:56: error: initialization of 'ssize_t (*)(const struct module_attribute *, struct module_kobject *, char *)' {aka 'long int (*)(const struct module_attribute *, struct module_kobject *, char *)'} from incompatible pointer type 'ssize_t (*)(struct module_attribute *, struct module_kobject *, char *)' {aka 'long int (*)(struct module_attribute *, struct module_kobject *, char *)'} [-Wincompatible-pointer-types]

is raised. This is fixed by adding the `const` specifier.
