lib/blkdev: add open_blkdev_or_file() function

Purpose of this function is to open a path that is potentially pointing to a
block device or file without races.  The function also proper open(3) flags
are used to check the device is not busy, and finally warning is been
printed if a block device happens to be misaligned.
