[PATCH] preloader: Extend low memory area a bit

[Arkadiusz Hiler]

SDL.dll which is shipped with Doom II on Steam has one of the fixup records
broken which causes relocation to fail on some Linux systems.

On Windows if we reserve that memory area before loading the DLL we experience
similar crash, and yet there are no bug reports for this dosbox.exe + SDL
combo.

The change here extends the low memory area over the DLL's base address (+ some)
to make sure that range is available.
