Prettify demo script

[gurjeet]

Added spaces to make the trailing line-continuation slashes all line up in the same column. Also moved a few command-line flags around to group together flags of same kind.

Note to reviewers: use command git diff -w to see the changes to exclude the whitespace diff.

@alexlarsson , others, please take a look at the minimal diff of rearranging lines; consider ignoring the whitespace diff during review by using the following link.

I personally think this doesn't make it any prettier, and the need to redo the lining-up every time a longer parameter is added is a practical annoyance.

This does maybe make sense, although the order of parameters to bwrap does matter - many of the parameters manipulate the filesystem in some way, in sequence - so I think sorting filesystem-affecting parameters by the part of the filesystem they affect (for example, keeping everything that touches /run together) is probably better-practice than sorting them by parameter name.
