reproducible: Don't look for youngest file when no source tarball
Some packages (eg. init-ifupdown) take their source files entirely from openembedded-core, that is, they download no source tarball. These recipes either don't use S at all (ie. it is empty at unpack time), or they set S = WORKDIR (as in init-ifupdown). Looking at the file timestamps in the WORKDIR causes a non-reproducible SOURCE_DATE_EPOCH, as files taken from file:// URIs do not have reproducible timestamps. If S == WORKDIR, we are better to assume that there is no source tarball, and to fall back to a fixed timestamp for the SOURCE_DATE_EPOCH. This makes the init-ifupdown build reproducible.
