[generators] flight_plan: fix for longitude > 107deg on 32bit systems

In ocaml an int is always signed it has only 31bits on 32bit systems...
So when trying to represent a longitude of more than 107 deg as 1e7deg it is more than the max_int of 1073741823
So always use an Int64 in the convert angle function to fix #808
