Summary

What does the PR accomplish, why was it needed?
A copy of kernel-mshv's vmlinuz in /boot/efi was formerly needed due to the mshv loader running entirely in the efi partition and being responsible for loading the kernel.

Nowadays, the mshv loader returns to grub which can change back to the rootfs partition and load the kernel from the normal location so this copy in /boot/efi is vestigial.

Change Log

• Remove /boot/efi/vmlinuz-* from kernel-mshv package

Does this affect the toolchain?

NO

Test Methodology

• Building now, to test end-to-end in kata scenario
