UefiPayloadPkg/BlSupportDxe: fix ReserveResourceInGcd() calls 

The last parameter of ReserveResourceInGcd() is "ImageHandle", forwarded
in turn to gDS->AllocateMemorySpace() or gDS->AllocateIoSpace() as "owner"
image handle.

But BlDxeEntryPoint() passes "SystemTable" as "ImageHandle".

Compilers have not flagged it because EFI_HANDLE (the type of
"ImageHandle") is unfortunately specified as (VOID*), and
(EFI_SYSTEM_TABLE*) converts to (VOID*) silently.

Hand the entry point function's "ImageHandle" parameter to
ReserveResourceInGcd(). This fixes an actual bug.
