e41fa8ef62 Revert renaming symbols in KernelSU driver
- In order to reduce the extra patch code and increase the rate of hunk succeed, we do not rename the symbols in KernelSU drvier but instead do it all in kernel/kallsym.c

- Make susfs_starts_with() global as it maybe useful in future

ef399712dc kernel: Introducing Tracepoint Hook Type Support
Tracepoint is a predefined hook point in the kernel, compared to Kprobe,
it is more stable and has lower performance overhead, although compatibility
is relatively poor, it is still worth trying

By the way, we have also included the config definitions related to hook types
in Kconfig, to enhance cleanliness

These patches is based on https://github.com/backslashxx/KernelSU/issues/5
