Added "SSHLibrary." qualifiers to state.py/utils.robot.

Someone had added the use of SCPLibrary to our code.  SCPLibrary
and SSHLibrary both have keywords with the same names.  This was
causing robot errors.  This is fixed by adding "SSHLibrary."
qualifier to keyword invocations like "Open Connection"
