Kernel: Fix boot profiling

Browse source 
Boot profiling was previously broken due to init_stage2() passing the
event mask to sys$profiling_enable() via kernel pointer, but a user
pointer is expected.

To fix this, I added Process::profiling_enable() as an alternative to
Process::sys$profiling_enable which takes a u64 rather than a
Userspace<u64 const*>. It's a bit of a hack, but it works.
