We now return failed in FrLdrMapImage if the file could not be read.

FreeLDR ARM now loads properly, however, we need to start building the ARM kernel and ARM boot drivers, otherwise their relocations will have byte offsets which will lead to alignment errors (on ARM relocaitons are DWORD-aligned).
Next steps are to get the kernel building, then the HAL, then bootvid/kdcom.
