Subject: [PATCH] generator: Add new virt-customize --tar-in operation

Using 'virt-customize --tar-in some.tar:/dir -a disk.img' will unpack
'some.tar' into '/dir' in the guest.  Note that this will not work for
compressed tar files as written since the underlying guestfs_tar_in
function requires the compression type to be set explicitly and
defaults to no compression (it does not auto-detect or default to
compression).

(cherry picked from commit b5f7b0ec18e30d25342bc322e571edf17a72974f)
