Fix eina_file_virtual_map_new function (/me glares at Frenchie).

- Spank Cedric !!!!!

NB: How about we actually fill in "map" after allocation ??

NB: Previously we would malloc "map" and immediately exit without
filling it in, without adding it to the hash....nothing. Just allocate
and get out. Bad Frenchie !!!
