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.
