[vhd] fix Rufus being unable to open .vhd images

Browse source 
* Due to a typo in vhd.c where the second safe_stricmp() should be against ".vhd" and not ".vhdx" again.
* Also enable the ignore boot marker bypass for VHD/VHDX/FFU and don't misreport those images as
  "compressed disk images".
* Closes #2309.
