When the SOURCE_DATE_EPOCH environment variable is set, use it to
override the timestamps of .ipk archive contents.
This ensures that .ipk archives built in environments without SCM
metadata (mainly the SDK) are reproducible between different runs.

When Package/xx/conffiles only contains directories that are empty at
package time, conffiles.resolved will be missing and the following
error messages will appear in the build log.
/home/yousong/git-repo/openwrt/openwrt/scripts/ipkg-build -c -o 0 -g 0 /home/yousong/git-repo/openwrt/openwrt/build_dir/target-mips_24kc_musl/linux-malta_be/openvswitch-2.10.0/ipkg-mips_24kc/openvswitch-common /home/yousong/git-repo/openwrt/openwrt/bin/packages/mips_24kc/packages
mv: cannot stat 'CONTROL/conffiles.resolved': No such file or directory
chmod: cannot access 'CONTROL/conffiles': No such file or directory
It will not break the ipkg-build process. The change is merely cosmetic
to not cause confusion when reading logs

Move the "which svn" and "which git" calls next to the timestamp commands
using those tools to not prematurely fail on systems where svn or git are
not present.

According to gzip 1.7 release note:
The GZIP environment variable is now obsolescent; gzip now warns if
it is used, and rejects attempts to use dangerous options or operands.
You can use an alias or script instead.
Fix this warning by using pipe instead

As a follow-up to r46026, this commit sets the modification
times of files inside the tarballs to deterministic values.
It uses the date of the last git or svn commit and falls
back to the old behavior if those are not available.

When creating control.tar.gz, data.tar.gz and $package.ipk
tar compresses them with default gzip options.
This includes build timestamps in their gzip headers.
By setting the GZIP env variable to -n, gzip no longer embeds
them, which is a step towards reproducibility.
