[Libguestfs] [PATCH virt-v2v 0/3] tests: Add a phony Fedora image for testing

When we split virt-v2v from libguestfs many moons ago, I copied the test-data/ subdirectory over. I didn't modify it much, and it contains much test data that is irrelevant to virt-v2v. (This change does _not_ clean up any of that ...) However we did use the phony Windows image (test-data/phony-guests/windows.img) to do a semblance of testing Windows conversions, or as much as can be done without having the proprietary operating system itself around. We never used any of the Linux images, and in fact (before this change) they could not be used. They simply don't appear close enough to a real guest to work with virt-v2v. In particular they lack installed kernels, modules, bootloader config and the program needed to rebuild the initramfs. This change fixes the Fedora image(s) so they can be used for testing, and adds conversion of those to the testsuite. I already pushed the first commit in this series since it was a big binary blob update to the phony Fedora RPM database that was not reviewable: https://github.com/libguestfs/virt-v2v/commit/0d1b2ec1b733db1ca0bebf2e4a9... Rich.
