Kernel: Improve open() POSIX compatability
...
Also rename Process::sys_creat -> create_file since it is not
actually a syscall and only used by open as a healper.

Kernel: Fix bug in disk writing
...
I have used two weeks in locating a bug in my ext2 implementation
while the bug was actually in disk write. If you called write_sectors
on disk it would write the first sector_size bytes repeatedly to all
asked sectors and this corrupted the disk...

Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

cmake is now filled with 'sudo' but with sudo timeout this should be
fine.
