[ms-sys] fix for detecting windows MBRs with localised messages

Browse source 
* Windows MBRs contain localised strings which mean the bytes between the
  executable code and the disk signature / partition table can change depending
  on locale. This patch adds lengths to reflect the offsets which are the same
  for every locale, and only compares these lengths when detecting existing
  Windows MBRs.
