kernel/module.c: use scnprintf() instead of sprintf()
For some strings, they are permitted to be larger than PAGE_SIZE, so
need use scnprintf() instead of sprintf(), or it will cause issue.
One case is:
if a module version is crazy defined (length more than PAGE_SIZE),
'modinfo' command is still OK (print full contents),
but for "cat /sys/modules/'modname'/version", will cause issue in kernel.
