[kvm-unit-tests PATCH v3 27/27] arm64: Add an efi/run script

[Nikos Nikoleris <nikos.nikoleris@arm.com>]

This change adds a efi/run script inspired by the one in x86. This
script will setup a folder with the test compiled as an EFI app and a
startup.nsh script. The script launches QEMU providing an image with
EDKII and the path to the folder with the test which is executed
automatically.

For example:

$> ./arm/efi/run ./arm/selftest.efi setup smp=2 mem=256
