Update image deploy directory artifact name

[masami256]

This pull request updated scripts/runqemu and classes/sdk-installer.bbclass files to follow Isar's ommit 13cb77d ("meta: Deploy image build artifacts into distro- and image-specific subdirs").
Before the commit, kernel, image, and initramfs name have -- prefix, but since the commit such prefix has been removed and artifact directory name has been changed.

Then, we got following errors when execute runqemu script or build sdk.

runqemu result:
