AP_HAL_Linux: Remove misleading constant 

The constant passed to cflag is BOTHER, meaning the actual baud is set
in the other specific members.  Don't define B* constants as they are
misleading here and this is why it doesn't work with e.g.
cfset[io]speed()... that function expect a B* constant which in Linux
is not the speed, but an index to an array with speeds.
