[OE-core] [PATCH] oe-selftest: Build wic runtime requirements and images before testing

[Ed Bartosh]

Some native tools (syslinux, parted, mtools, etc) are required
by wic to produce images. Unit tests fail if the tools are
not available.

Baked tools and image-core-minimal used by wic before running tests.
