Fix FBXConverter: use proper 64-bit constant

Use proper 64-bit constant for CONVERT_FBX_TIME(time) conversion, fixes:

  code/FBXConverter.cpp:2025: error: integer constant is too large for 'long' type
  code/FBXConverter.cpp:2026: error: integer constant is too large for 'long' type
  code/FBXConverter.cpp:2794: error: integer constant is too large for 'long' type
  code/FBXConverter.cpp:2868: error: integer constant is too large for 'long' type
  code/FBXConverter.cpp:2878: error: integer constant is too large for 'long' type
  code/FBXConverter.cpp:2888: error: integer constant is too large for 'long' type
