runInLinuxVM: re-add sourcing of stdenv & .attrs.sh

Browse Source 
This is required for `preVM` which can be arbitrary code: e.g.
`vmTools.createEmptyImage` assumes the presence of `$out` in its default
configuration.

Also, before this patch, `preVM` wasn't even set in the
`__structuredAttrs` case.
