daemon: Reimplement 'part_get_mbr_part_type' API in OCaml.

Browse Source 
Instead of parsing 'parted' output OCaml implementation relies on the following facts:

1. MBR partition table can hold up to 4 "primary" partitions.
2. Partition with number greater then 4 is "logical" partition.
3. Partition with number less then or equal to 4 with MBR ID 0x05 or 0x0f is "extended" partition (http://thestarman.pcministry.com/asm/mbr/PartTypes.htm; https://en.wikipedia.org/wiki/Partition_type) or "primary" otherwise.
