Load the bootstrap blob at 4096 instead of 0
...
This way the NULL page can stay unmapped and the bootstrap code can
avoid UB when reading the initfs header (which is at the start of the
bootstrap code.

Remove Context::vfork.

Since clone is no longer exists as a syscall, it makes little sense to
manage vfork in the kernel. Implementing vfork in userspace would still
be possible.

Turns out the problem all along was that the ActivePageTable was never
dropped in usermode_bootstrap. So as soon as any other hardware thread
tried to do page table business, it deadlocked!
