Currently the environment handling for terminals is inconsistent. There
are two fixes here:

a) Ensure the environment is setup before all oe.terminal call

b) Actually set the environment before the spawn calls since we need
variables like DISPLAY when the commands are being executed, not just
within the terminal environment. If this doesn't happen, DISPLAY can end
up not set with the errors that brings with it when trying to run X
commands.
