Linux: fall back to FUSE when dmsetup is not installed (#1898)

Browse Source 
Without dmsetup, MountVolumeNative fails with "dmsetup not found in
system directories" instead of using the FUSE path, so on systems that
do not ship device-mapper tools (for example OpenWrt) every mount and
the filesystem formatting step of --create need an explicit
--mount-options=nokernelcrypto. Treat a missing dmsetup like the other
cases where kernel crypto cannot be used.
