This is one of two patches to get Fallout 4 Script Extender working in wine. f4se allocates memory for trampolines in the spaces before the Fallout4 exe image and the f4se dll image. This patch:

Fix VirtualQuery rejecting any blocks before the image as already allocated (it looks like get_free_mem_state_callback sees blocks before the exe base address as overlapping the exe base from calculating the block end address as block start address + size, ie a 256 byte block starting at 0x100 would "end" at 0x200).

Apparently it also get SkyrimSE script extender working, but I don't own that so I can't test that.
