gdb: define COFF file offsets with file_ptr
The arguments to these functions are file_ptr, so these declarations
were accidentally implicitly down-casting them to signed int. This
allows for reading files between 2 and 4 GB in size in my testing (I
don't have a larger dll currently to test). These may not be natively
supported by Windows, but can appear when using split-dwarf information.
This solves a "can't get string table" error resulting from attempting
to pass a negative offset to bfd_seek. I encountered this occuring while
trying to use a debug file for libLLVM.dll, but searching online reveals
at least one other person may have run into a similar problem with
Firefox?

With this patch, the debug file appears to load successfully and I can
see debug information in gdb for the library.
