[OE-core] [PATCH 3/3] oe.terminal: improve how we spawn screen

[Chris Larson]

From: Chris Larson <chris_larson at mentor.com>

- Name the screen session 'devshell', to avoid confusion if running bitbake
  itself under a screen session.
- Display a warning message when spawning screen, so it's clear to the user
  that screen has been run (otherwise do_devshell just appears to hang).
