build: store granular timestamps in packages
With the new `SOURCE` argument of `get_source_date_epoch` it is possible to set package timestamps based on actual package changes rather thane $TOPDIR changes. This commit adds a new variable PKG_SOURCE_DATE_EPOCH which is used by the `ipkg` build script. As a fallback the existing SOURCE_DATE_EPOCH is used or as last resort the current time. The redundant checks for `.git/` and `.svn/` are removed. Signed-off-by: Paul Spooren <mail@aparcar.org>
