Progress bars jump when percentages are the label

[garrett]

On at least the software page, possibly on other places, the progressbar width shifts as the numbers increment.

The proper solution would be to use tabular numbers, but our font does not support that (yet). Related: #15090 & RedHatOfficial/RedHatFont#27

Therefore, a work-around that we could do right now is to set min-width: 3ch on the label. As this would affect anything with a progress bar, we should probably have this as an override.

For the "Software Updates" case I reproduced the issue using the testUpdates.testBasic test case and extending it with:

+        for i in range(1, 35):
+            pkgname = "test{}".format(i)
+            self.createPackage(pkgname, "1.0", "1", install=True)
+            self.createPackage(pkgname, "1.0", "2", postinst="sleep 1;")
         # create two updates; force installing chocolate before vanilla

This makes the issue visible for me.
