Fixed an error in the SukiSU integration of the Kirin 970 HarmonyOS2 kernel source code:

Browse Source 
- Error: In the Kirin 970 HarmonyOS2 kernel source code, integrating SukiSU requires disabling the CONFIG_HKIP_SELINUX_PROT configuration option. Disabling this option will enable the use of flex_array. However, in the add_type and add_typeattribute_raw functions in kernel/selinux/sepolicy.c, if a Huawei HISI device is detected, ebitmap not flex_array is used, causing an error.

- Fix: Added conditional checks to the add_type and add_typeattribute_raw functions in kernel/selinux/sepolicy.c. Because the Kirin 970 EMUI10 kernel source code does not use flex_array, an option defined only in the EMUI10 kernel configuration is added to determine the kernel source code version.
