virshtest: Adapt 'virsh-read-bufsiz' and 'virsh-read-non-seekable'
Test both situations (reading from non-regular file and reading a file larger than (arbitrary) buffer size) via 'virshtest'. To feed the pipe we need to create a thread that does it, but otherwise it's fairly straightforward. Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
