build: don't store timestamps in APK packages
This commit statically sets SOURCE_DATE_EPOCH to 0, which causes `apk mkpkg` to
drop the date from generated packages. This improves reproducibility while
leaving package specific SOURCE_DATE_EPOCH untouched. The latter can be
interesting for i.e. packages like busybox, which prominently show that date on
the login shell.
Without this commit, packages that live inside feed repositories (openwrt.git,
packages.git etc) like `mtd` or `attendedsysupgrade-common` would have random
timestamps since no "full" git log was available.
Below an example with different source dates (0, 1):
│ 0755 root:wheel - - /
│ 0755 root:wheel - - lib/
│ 0755 root:wheel - - lib/apk/
│ 0755 root:wheel - - lib/apk/packages/
│ -0644 root:wheel 1970-01-01T00:00:01Z 10 lib/apk/packages/mtd.list
│ +0644 root:wheel - 10 lib/apk/packages/mtd.list
│ 0755 root:wheel - - sbin/
│ -0755 root:wheel 1970-01-01T00:00:01Z 24595 sbin/mtd
│ +0755 root:wheel - 24595 sbin/mtd
