Raise a flag when we must rebuild KDE packages because of a QT update

Created by: ollieparanoid

Whenever Alpine updates its qt5 packages, we must upgrade the qt5-* packages we have in our aports folder as well, otherwise they become incompatible. In #976 I have added a pmbootstrap testcase for that, so we should notice it pretty soon at least (the testsuite runs with every new commit and PR, so at the current rate at least once a day).

According to @bhush9, we need to update the following KDE packages, whenever a qt package gets upgraded, too:

• kwin
• plasma-integration
• kwayland

there is rebuild.list in qt5-base packaging (at least for arch)

@awilfox: Do you know if Alpine has a similar mechanism to such a rebuild.list file? And how does Adelie handle this?

If we can't find a better solution, the APKINDEX files store the timestamp when a package was built. We could add a pmbootstrap test, that checks if kwin etc. have a more recent timestamp than qt5-qtbase from Alpine.
