Daniel Hilst a2378ba780 build: Make builds deterministic
Port SOURCE_DATE_EPOCH patterns from xcat-core to all xcat-dep build
scripts. RPM and Debian packages now produce identical output given
the same Gitepoch timestamp, regardless of build host or time.

EL (RPM) changes:
- mockbuild-all.pl: --build-timestamp flag, deterministic run_id,
  tar --sort/--owner/--group/--mtime, createrepo --revision
- All mockbuild.pl: SOURCE_DATE_EPOCH cascade (CLI > Gitepoch > git > time),
  deterministic mock config with SOURCE_DATE_EPOCH in chroot env,
  RPM macros for timestamp clamping and fixed buildhost
- goconserver: -trimpath -buildvcs=false, canonical rpmbuild path
- xnba: canonical rpmbuild path
- syslinux: ZERO_AR_DATE=1 in mock env

Ubuntu (Debian) changes:
- All make_deb.sh: SOURCE_DATE_EPOCH fallback from Gitepoch
- goconserver: deterministic SNAP_TS and changelog from epoch,
  -trimpath -buildvcs=false in debian/rules
- syslinux: -fdebug-prefix-map for path-independent debug info
- build-apt-repo.sh: gzip -n, Release Date: from SOURCE_DATE_EPOCH

Verified: 31/33 package artifacts produce identical SHA256 hashes
across independent builds. 2 syslinux sub-packages (devel,
debugsource) have known limitations from upstream build system.
