- Clear KPCR->TEB during bootstrap as well.
- Use KPCR_PROCESSOR_NUMBER instead of 0x130.

Log:
- Add two more lines in boot.S which detect boot-by-NTLDR and jump into KiSystemService (I thought FreeLdr didn't use the entrypoint, but it looks like it does, so this hack is needed). Detection is done by checking for the high bit in the PLOADER_PARAMETER_BLOCK pointer, which will be set on NT.
- Fix a double bug in KiSystemStartup. First, we were setting KPCR->Number instead of KPRCB->Number. Second, we were using KeGetPcr instead of __writefsdword. It worked on ROS because KeGetPcr is hard-coded to ROS's KPCR buffer.
