Remove VS specific #pragma comment (lib, ...).

This Visual Studio specific pragma hides missing library references
on Visual Studio builds, but since comctl32 is not the only necessary
Windows dll and this has never been extended to other libs, this pragma
is unnecessary and potentially confusing, so I removed it.

Documentation of dependencies mentions comctl32 (and more) and future
CMake generation of user project VS IDE files can reference the FLTK
dependencies by internal (CMake) means anyway.
