[Libguestfs] FYI: cryptsetup luksOpen now requires loads of RAM

https://gitlab.com/cryptsetup/cryptsetup/issues/488 This prevents virt-* tools from opening encrypted partitions automatically. Even 1024M isn't sufficient. I had to bump the memory up to 1400M to make it work, which is just too big for routine use. Even worse if the RAM size isn't quite large enough (eg 1200M) cryptsetup crashes. I'm not sure what to do about this now. The worst aspect is probably the lack of any error message from cryptsetup when it fails, but this is at least the easiest to fix because we can catch the exit code and turn that into an error message.
