tests: Support runtime-rs QEMU cmdline format in attestation test

Browse Source 
The k8s-confidential-attestation test extracts the QEMU command line
from journal logs to compute the SNP launch measurement. It only
matched the Go runtime's log format ("launching <path> with: [<args>]"),
but runtime-rs logs differently ("qemu args: <args>").

Handle both formats so the test works with qemu-snp-runtime-rs.
