[OE-core] [PATCH] terminal.bbclass: use SHELL to interpret the init script

[Li Zhou]

/bin/sh was used to interpret the init script of the new terminal, below
issue occurs when SHELL="/bin/bash" and /bin/sh is linked to /bin/dash:
function foobar { echo foobar; };
export -f foobar
bitbake -c devshell virtual/kernel
Then the devshell fails to be started because "export -f xxx" is wrong
for dash.

So start the new terminal using SHELL to interpret the init srcipt,
which can solve the issue caused by the difference between SHELL and
/bin/sh.
