Rework build system

Browse Source 
Replace the dpkg-buildpackage / debhelper rig with the same pattern
used in vpp-maglev and govpp-snmp-agentx: a Makefile that
cross-compiles CGO-free static binaries for amd64 and arm64, plus a
debian/build-deb.sh that stages the .deb directly with dpkg-deb. The
two arch packages drop into build/ and run on any glibc/musl Linux of
the matching arch.

VERSION is parsed once from debian/changelog and injected at link
time via -ldflags "-X 'main.Version=...' -X 'main.Commit=...' -X
'main.Date=...'", so 's3-genindex -version' is the source of truth
for which build is running. The Version constant in main.go becomes
a var to make this work; the old sync-version make target is gone.

Removes the now-unused debian/{control,rules,install,compat} files
and the matching debhelper artifact entries from .gitignore. build/
is added to .gitignore.

# Build one s3-genindex .deb for one architecture.
# Usage: build-deb.sh <package> <amd64|arm64> <version>
#
# The version is also baked into the binary at link time (see Makefile
# LDFLAGS), so `s3-genindex -version` is the source of truth for "which
# build". The .deb itself only carries the release version.
