syncqt makes invalid headers.pri for ActiveQt

After running syncqt, the file include/ActiveQt/headers.pri contains the following bogus line:

SYNCQT.HEADER_FILES = qaxbase.h qaxobject.h qaxscript.h qaxselect.h qaxwidget.h qaxaggregated.h qaxbindable.h qaxfactory.h qaxtypes.h ../../../../../../../../../../../../../../../../../../../include/ActiveQt/ActiveQt

The number of "../" in the last entry on the line is incorrect. This appears to be due to the following line in the modules hash in syncqt:

"ActiveQt" => "$basedir/src/activeqt/container;$basedir/src/activeqt/control;$basedir/src/activeqt/shared",

The code in syncqt that uses the data in the modules hash thinks that each entry contains a single pathname, not three paths concatenated path names as in the line above.
