astro/qmapshack: Update version 1.12.3=>1.13.0

• fix libproj detection: Our graphics proj is built with autotools and thus does not install it's cmake files. Patches provide an alternate method for finding libproj using pkg-config, see: https://sourceforge.net/p/qlandkartegt/mailman/message/36639866/
• fix a crash with current Qt when no GPS device is found (which at least for me is the default case): since the last Qt update, QList aborts on an assertion when trying to access the first element of an empty list.
