sstate-diff-machines.sh: support rpm, deb and tar package types in analysis
The sstate-diff-machines.sh script's --analyze option was only supporting
ipk packages, this adds rpm, deb and tar packages, checking all the used
package types simultaneously.
Without this changing sstate between machines would not report an error
if the difference occured in packages and ipk packaging was not enabled.
