kernel-fitimage.bbclass: do_assemble_fitimage(): cd to $B

Prior to assembling the fitimage, ensure that $B is the cwd due to
bitbake commit 67a7b8b021badc17d8fdf447c250e79d291e75f7 "build: don't
use $B as the default cwd for functions".

Without this change, do_assemble_fitimage() fails like:

Log data follows:
| DEBUG: Executing shell function do_assemble_fitimage
| arm-ka-linux-gnueabi-objcopy: 'vmlinux': No such file
| WARNING: exit code 1 from a shell command.
| ERROR: Function failed: do_assemble_fitimage
