Subject: [PATCH] contrib: support disabling "LTO" in "nm-copr-build.sh"

The "nm-copr-build.sh" script is run by our copr to generate the SRPM of
NetworkManager (via `curl ... | bash`).

Building with LTO takes a long time, for testing it can be nice to disable
that. Add an environment variable for that. It can be used when manually
building an RPM in copr.

(cherry picked from commit 0566e9dc63fbd7cffd9d1c738b67a7a3d0b9e870)
