devtool: force use of bash when running build within extensible SDK

Browse Source 
Ubuntu's default dash shell causes oe-init-build-env to behave a bit
differently - (a) it can't pick up the OE root directory and (b) it
can't see any build directory specified as a command-line argument
(since dash doesn't pass through any arguments specified to sourced
scripts). We could work around these but doing so requires some internal
knowledge of the script; a much simpler fix is just to force running the
command under bash since it's expected to be installed on every distro.

Thanks to Chen Qi <Qi.Chen@windriver.com> for this fix.

Fixes [YOCTO #7614].
