Fixed serial support in 2.6 (too much work for...)

Removed bootloader and just wrote command line into linux kernel

base/inifile.cc:
    the forked process should not return, it should exit.
dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
    The serial port in reality has some delay and linux expects it. This
    schedules an interrupt 300 cycles after the transmit instead of
    immediately
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
    removed boot loader and stuck boot command line in the kernel manually
