common: partitions: record whether disk is GPT or MBR partitioned
Currently, the only way to differentiate between a GPT disk and a MBR
one is to check whether the cdev's device has a guid (=> GPT) or a
nt_signature (=> MBR) device parameter. We already have a flag parameter
though, so let's record this info there for easy retrieval.
We intentionally don't use the struct cdev::filetype member, because
we don't want to change behavior of file_detect_type().
