[modes] obs-rpm-build+pp: Move up tools prefix

[Thaodan]

If the tools prefix isn't moved up their is a chance that programs which should
be executed under the tools policy is run under the target because the path is
for example in the sbox_user_home.

I guess the issue you describe may only happen when you are using sb2 directly on host, without the SDK, right? When used under the SDK, tools are always bind-mounted under the unified /srv/ hierarchy specifically to avoid this sort of issues :)

obs-rpm-build (without +pp) does not need this fix? And the other modes? (Haven't checked)

It depends on where you safe your targets. You can also face the same issue under the SDK if you use sb2 init on a target in home.

obs-rpm-build already has the prefix that this position so doesn't have the issue.

If the other modes use this order, then there is no question about :)

I would suggest this message instead: "Fix tools prefix priority"

I would appreciate having a bz item linked here, where I could report time - please create one.

After that it LGTM.
