[oe-core][PATCH 1/1] terminal.bbclass: force bash for devshell

[Joe Slater]

Since shell_trap_code in build.py sets /bin/sh as the interpreter
we will die a silent death if our environment contains things like
"export -f bodilyfunction" and /bin/sh is really /bin/dash.

Fixes this for the case of devshell.
