common: fix mbr filetype detection
Sometimes mbr is erroneously recocognised as FAT partion. Due to this the mbr partition parser is not being called and the partitions on the media are not detected. This patch should fix the problem. The checking is done as in the linux kernel. I have seen the problem using usb sticks. Although partitioning and formatting them under linux. The file system type field in the mbr remains there which causes the wrong detections as FAT32 type and not as mbr.
