Subject: [PATCH] t/lib-httpd: switch SANITY check for NOT_ROOT
[...]
We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS. Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:
1. we know we are root
2. we know we are not root
3. we could not tell, because `id` was not available
We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

That looks good to me and worked as expected when I tried it.
