Preserve supplementary groups of build users
The following patch is an attempt to address this bug (see
<http://bugs.gnu.org/18994>) by preserving the supplementary groups of
build users in the build environment.
In practice, I would expect that supplementary groups would contain only
one or two groups: the build users group, and possibly the “kvm” group.

Allow substitutes for builds that have preferLocalBuild set
Not substituting builds with "preferLocalBuild = true" was a bad idea,
because it didn't take the cost of dependencies into account. For
instance, if we can't substitute a fetchgit call, then we have to
download/build git and all its dependencies.
Partially reverts 5558652709f27e8a887580b77b93c705659d7a4b and adds a
new derivation attribute "allowSubstitutes" to specify whether a
derivation may be substituted.
