feat: packagechooserq is built with the ISO (build-calamares-modules.sh) instead of a committed .so; the Steamify page is left out when Calamares' version differs from the one it was built for

+# build-calamares-modules.sh: builds Calamares' packagechooserq module (the
+# QML page the Steamify page runs in) for the ISO. CachyOS's
+# cachyos-calamares-next leaves it out of its own build, so it's built here,
+# out of tree, from CachyOS's Calamares source against the installed
+# cachyos-calamares-next, and installed into airootfs. Run as root in the
+# build container, before buildiso.sh: the package comes from the same repos
+# at the same time as the ISO's, so the module matches the ISO's Calamares.
+# Records the version it was built for next to it (calamares-online.sh
+# compares that with the Calamares it ends up with).
