[meta-oe][PATCH 2/3] kernel-selftest: Convert to use a dedicated UNPACKDIR

[Khem Raj <raj.khem@gmail.com>]

Avoid following warning by using a dedicated unpack directory for sources.

WARNING: kernel-selftest-1.0-r0 do_unpack: kernel-selftest: the directory ${WORKDIR}/${BP} (/home/kraj200/yoe/build/tmp/work/qemux86_64-yoe-linux/kernel-self test/1.0/kernel-selftest-1.0) pointed to by the S variable doesn't exist - please set S within the recipe to point to where the source has been unpacked to
