[OE-core] [PATCH] cml1.bbclass: explicitly set workdir

[André Draszik]

bitbake rev 67a7b8b02 "build: don't use $B as the default cwd for
functions" (included in current bitbake master) breaks the assumption
that do_menuconfig / do_diffconfig run inside the build directory.

This causes these tasks to fail as they're being executed in the
wrong directory.

Set workdir explicitly.
