[meta-oe][PATCH v3] image_types.bbclass: fix cpio IMAGE_CMD to preserve working directory

[Jonathan Liu <net147@gmail.com>]

The working directory is changed in a subshell when executing cpio to
preserve the working directory for any subsequent commands. This is to
keep the working directory consistent when generating multiple image
types.
