[kernel] Clean up syscall code

Browse Source 
This is a minor refactor including:
- Removing old commented-out syscall_dispatch function
- Removing IA32_EFER syscall-enable flag setting (this is done by the
  bootloader now)
- Moving much logging from inside process/thread syscalls to the 'task'
  log area, allowing for turning the 'syscall' area down to info by
  default.
