In the BareboxDriver, UBootDriver, and SmallUBootDriver, the option sent to the bootloader to interrupt boot loading is done with some form of:

self.console.write(interrupstring.encode('ASCII'))

According to the documentation

use \x03 for CTRL-C
or
use “\x03” for CTRL-C

Neither of these work.

After using labgrid-client -vv I see the following is written to the console

CONSOLE SerialLogger.ma:   SerialDriver(main) > \x03␍␤
DEBUG   SerialDriver(ma:   Write 4 bytes: b'\\x03'

or

CONSOLE SerialLogger.ma:   SerialDriver(main) > \\x03␍␤
DEBUG   SerialDriver(ma:   Write 5 bytes: b'\\\\x03'

Neither of which is correct and causing the boot loader not to be interrupted.

Checks to see if the interrupt string starts with \x and when that
is the case, converts the remained of the string to a bytearray before
sending the interrupt to the boot loader.
