terminal.bbclass: do not export PS1
With a complex PS1 setup, PS1 might not have all characters correctly escaped when terminal.bbclass writes the export. This caused the run.do_terminal.PID to terminate, making it impossible to use the devshell. As the spawned shell will parse e.g. .bashrc (or whatever rc-file is being used), PS1 will be reset in the devshell.
