sshcontrol: Use os.environ.copy() instead of copy.copy()
os.environ is special and copy.copy() doesn't do what we'd expect,
changes in the child object change the parent. copy.deepcopy() is
also known to have issues with it.
Use the dedicated .copy() method which will not influence the
parent. This fixes selftest failures where the DISPLAY variable
disappears.
