guix package: Export 'transaction-upgrade-entry'.

Browse source 
* guix/scripts/package.scm (transaction-upgrade-entry): Add 'store'
parameter and use it instead of (%store).  Export.
* tests/packages.scm ("transaction-upgrade-entry, zero upgrades")
("transaction-upgrade-entry, one upgrade")
("transaction-upgrade-entry, superseded package"): Adjust accordingly.
