lmcp deb: reproducible build via SOURCE_DATE_EPOCH

Browse Source 
reprepro refuses to re-include a .deb if the bytes differ from one
already in pool/. Fixed mtimes via SOURCE_DATE_EPOCH make subsequent
builds byte-identical, so CI re-runs of the same pkgver/pkgrel are
accepted as no-ops instead of failing.
