gps.c: Make two more memory leak fixes and a small coding style change

1)
add_gps_point():
Apparently osm_gps_map_point_new_*() is leaking memory if the
point struct is not freed after the point is added to the
map osm_gps_map_track_add_point().

However the API for releasing a point is missing on
older Windows builds of the map library, so instead of
osm_gps_map_point_free() we simply call:
	free((void *)point);

2)
init_map()
According to memory management tools
osm_gps_map_get_default_cache_directory() is using g_realloc
for eventual string expansion therefore we have to release at the
returned pointer.

3)
add_gps_point()
Also a small coding style change is made:
move the pointer symbol (*) near the name of the variable
instead of leaving spaces on both sides, like:
<type> * <name>
