Enhance runqemu to detect and decompress .zst-compressed rootfs images
(e.g. ext4.zst, wic.zst) automatically. If a decompressed image already
exists in the original directory, it will be reused to avoid overwriting
build artifacts. Otherwise, the image is decompressed and removed after
the QEMU session ends.
This allows runqemu to be used seamlessly with compressed image formats
generated by the build system or during releases.
Note: support for .zst images is only available when snapshot mode is
enabled
IMPORTANT:
This patch assumes that the original directory of the .zst-compressed
image is writable. If, for some reason, the path passed from CI or
another system to the script is read-only, the decompression step will
fail when trying to write the uncompressed image to the same directory.
