Subject: [PATCH] run-vmtest@v2: remove unused img input, make vmlinuz optional

Previously the first run-vmtest action step would always search for
vmlinux image in KERNEL_ROOT, and then copy it to path specified by
inputs.vmlinuz

However, the caller may want to pass vmlinux image directly.

Change this behavior: search only inputs.vmlinuz was not passed.
