kernel: Modify KERNEL_SU_VERSION logic and behavior (#696)

Browse Source 
This patch modifies the following:
- Move the version addition logic in ksu.h to Makefile processing
- Print the current version number of KernelSU during make build

build test (normal):
 buildlog:
HOSTCC scripts/basic/bin2c Using .. as source for kernel -- KernelSU
version: 11055
  CHK     include/generated/utsrelease.h
  UPD     include/generated/utsrelease.h

 KernelSU software:
  KernelSU Working Version: 11055 (v) Superusers: 0 Modules: 0


![11055](https://github.com/tiann/KernelSU/assets/47409494/10506289-04d2-41c0-bd48-bad9f0dbdec5)

build test (missing .git file):
 buildlog:
HOSTCC scripts/basic/bin2c Using .. as source for kernel
../drivers/kernelsu/Makefile:23: "KSU_GIT_VERSION not defined! It is
better to make KernelSU a git submodule!"
  CHK     include/generated/utsrelease.h
  CHK     scripts/mod/devicetable-offsets.h

 KernelSU software:
  KernelSU Working Version: 16 (v) Superusers: 0 Modules: 0

The current kernel version 16 is too low for the manager to function
properly. Please upgrade to version 10977 or higher!
