Bootstrapping: don't use convenience symlinks

When `compile.sh` builds bazel using bazel, it
copies the resulting binary to `output/bazel`.
However sometimes the convenience symlink
`bazel-bin` is not created, probably because an
old one is still around and cannot be deleted.

That is clearly a bug, but to work around it, the
bootstrap builder shouldn't attempt to rely on the
creation of these symlinks in the first place.

This change updates compile.sh to use `bazel info`
to locate the `bazel-bin` directory's real path,
and attempt to copy the bazel binary from there.

This works around
