Extract the kernel configuration file parsing logic from feature.c into a new read_kernel_config() function in common.c. This includes: 1. Moving the config file handling and option parsing code 2. Adding required headers and struct definition 3. Keeping all existing functionality The refactoring enables sharing this logic with other components while maintaining current behavior. This will be used by subsequent patches that need to check kernel config options.

Adjust symbol matching logic to account for Control-flow Enforcement Technology (CET) on x86_64 systems. CET prefixes functions with a 4-byte 'endbr' instruction, shifting the actual hook entry point to symbol + 4.
