New variable to test SOL over ssh using port 22

   -This added a new variable OPENBMC_CONSOLE_CLIENT  that is empty
 by default
   -The new variable allows the SOL tests to be executed using the
port 22 instead of port 2200, to do this is necessary execute the
obmc-console-client instead of shell.
   -Also using a variable is possible to execute another console
client in the future
   -Strip returning string cmd to removed the space that I added at
the end

  Test:

Run the SOL test setting:

HOST_SOL_PORT=22 and
OPENBMC_CONSOLE_CLIENT="obmc-console-client"
