build: Set 'NIX_BUILD_HOOK' only if offloading is configured.

Browse source 
This prevents libstore/build.cc from executing nix/scripts/offload, which is
always created by config.status, when offload support is not enabled.

* build-aux/pre-inst-env.in: Export 'NIX_BUILD_HOOK' only when
configured; unset it otherwise.
