Move %configure and associated steps to %build

%configure and friends invoke code that is part of the package
and should be in %build.

If https://src.fedoraproject.org/rpms/redhat-rpm-config/pull-request/172
is merged, %configure would start throwing an error. This change
is proactively to avoid a later build failure. No rebuild will
be done.
