resolves: rhbz#2190276
Also synch copy-patches.sh with the later version from virt-v2v c9s.
I had to hand-hack the patches which touch common/ because they touch
some directories that are not listed as SUBDIRS by libguestfs, so not
included in the tarball. Hopefully this will go away when upstream
stable-1.50 does a new stable release.
