[OE-core] [PATCH] kernel: fix the modules tarball when using usrmerge

[Allen Wild]

kernel_do_deploy only uses /lib when creating the modules tarball,
creating an empty archive if usrmerge is in distro features because the
modules are in /usr/lib.

Create the modules tarball from ${D}${root_prefix}/lib instead of
${D}/lib so that it's not empty when usrmerge is enabled.
