SukiSU-Ultra/kernel/Makefile
JackAltman 328b4012b9 feat: detect proc_ops support via header parsing instead of version check. (#411) 
Some kernels (e.g. 5.4 with backports) include proc_ops despite being
older than 5.6.0. Replace hardcoded version check with runtime header
detection to handle these cases.

- Check for "struct proc_ops" in include/linux/proc_fs.h
- Use KSU_COMPAT_HAS_PROC_OPS macro for conditional compilation
- Fixes build failures on kernels with backported proc_ops
