t/lib-httpd: switch SANITY check for NOT_ROOT
The SANITY prerequisite is really about whether the filesystem will respect the permissions we set, and being root is only one part of that. But the httpd tests really just care about not being root, as they are trying to avoid weirdness in apache (see a1a3011 for details). Let's switch out SANITY for a new NOT_ROOT prerequisite, which will let us tweak SANITY more freely. 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.
