libfdisk: add fdisk_save_user_grain()
Let's provide API for applications that don't want to use the default
1MiB grain. The new function allow to use "as minimal as possible" if
grain is set by fdisk_save_user_grain() to 512.
If the phy sector size (or minimal I/O size) is greater than specified
grain size than smallest possible setting is used.
