feat: ulibc extensions for DOOM — mmap, munmap, ioctl, nanosleep, clock_gettime

Added userspace wrappers required for the DOOM port:
- sys/mman.h + mman.c: mmap() and munmap() for framebuffer mapping
- sys/ioctl.h + ioctl.c: ioctl() for framebuffer info queries
- time.h + time.c: nanosleep() and clock_gettime() for frame timing

All wrappers use the existing INT 0x80 syscall interface.
