Detect kernel version before swap file creation (#428)
According to man page `man 8 swapon', "Preallocated swap files are
supported on XFS since Linux 4.18". This patch checks for kernel version
before attepting to create swapfile, using dd for XFS only on kernel
versions <= 4.18 or btrfs.
Add new func util.kernel_version which returns a tuple of ints (major, minor)
