app/publisher/js/zsearch.go: do not track in git
app/publisher/js/zsearch.go: do not track in git

If we keep app/publisher/js/zsearch.go, when running make.go, it first gets mirrored into
CAMLI_ROOT/tmp/build-gopath-nosqlite/src/camlistore.org/app/publisher/js/zsearch.go
, with the same modtime as app/publisher/js/zsearch.go.

Then in genSearchTypes,
CAMLI_ROOT/tmp/build-gopath-nosqlite/src/camlistore.org/app/publisher/js/zsearch.go gets
regenerated anyway, because its modtime is older than that of
CAMLI_ROOT/tmp/build-gopath-nosqlite/src/camlistore.org/pkg/search/describe.go

Then in a subsequent run of make.go, the mirroring overwrites the newly regenerated file,
because its modtime is different (indeed, it is newer) than that of
app/publisher/js/zsearch.go

And the cycle repeats ad vitam eternam.

I think if we added app/publisher/js/zsearch.go to mirrorIgnored, it
might fix the problem, but I don't see the point in even keeping
zearch.go in git at all, so I propose with this CL to simply remove it.

If removed, it is simply generated at the first make.go run, and never
again afterwards (except if pkg/search/describe.go changes).

Fixes #957
