Subject: convert: linux: Add support for Zstandard compressed kernel modules

OpenSUSE uses *.ko.zst for kernel modules.  This commit adds support
in the same way as the existing support for *.ko.xz.  Note this
requires a corresponding change to libguestfs to support Zstandard
compression in the guestfs_file_architecture API:
