Fix up sudo wildcard copy

There are a few places where we do "sudo cp /foo/* $BASE/logs" which
doesn't work when the user can't access /foo/* to expand the
wild-card.

Convert these to use a "cp -r" of the directory.

There's no reason to assume qemu is the only virt-type used
(seeIeb3e20e8c70155ed2ee73e632df7f271212ed3a6), so just copy all
libvirtd logs and leave the hierarchy alone -- anything in there is
very likely to be helpful for forensics of failures.
