uboot-sign: do_concat_dtb(): cd to $B

Prior to running oe_runmake make sure $B is the cwd. This is required
due to bitbake commit 67a7b8b021badc17d8fdf447c250e79d291e75f7
"build: don't use $B as the default cwd for functions".

Without this change, do_concat_dtb fails with:
| ERROR: oe_runmake failed
| make: *** No targets specified and no makefile found.  Stop.
