macos-remote-build: stop rsyncing 850M of caches to the builder

The working-tree sync excluded two of the three gitignored
vendor/libghostty-vt zig caches but not zig-pkg/ (354M), so every
run silently re-pushed it. With rsync -a and no progress output that
looked like a hang on the rsync step.

Add the missing zig-pkg/ exclude (keeping the list in step with
.gitignore), plus web/ (~430M landing page/demo) and tests/fuzz/
(~120M corpus), neither of which is an input to `make all` -- all
the builder runs. Cuts the sync from ~1.2G/48k files to 350M/9.6k.

Only affects the default working-tree mode; REF=<tag> builds check
out on the builder via git and were unaffected.
