Small fixes to the packaging script

* Add a .tag file to the archive that contains the sha1 the package was created from. This is useful for diagnostics.
* Use bash and enforce error handling (it's easy to accidentally include bashisms)

Fix package builds against release builds of Qt

The Qt build system assumes that when building a module against a release
build of Qt, syncqt was already run at package creation time. So we have to
run syncqt when creating source packages.

This patch changes the syntax to separate the file name base from the
package version to use.
