m/installer/test: prevent QEMU file lock race

Albeit rare on development machines, this flake showed up frequently in
CI. QEMU processes weren't being waited on to finish before the next VM
launch, leading to multiple processes attempting to lock the same file.

In addition, a go-diskfs image handle wasn't being closed, though only
in a read-only context.
