tests/basic: fix basic tests on multi-arch

Only test UEFI on x86_64 and aarch64. Only test UEFI Secure Boot on
x86_64. Don't force the `bios` firmware for the NVMe test; instead, let
the QEMU code pick the default firmware for the given architecture.

Follow-up to 6775ab1 ("mantle/kola: copy basic tests into formal kola
workflow").
