[ADDED] Symlink for deb/rpm packages

Since v2.7.4 and due to an update of the goreleaser tool, the
server is now installed under "/usr/bin" instead of "/usr/local/bin".

We keep the install in "/usr/bin" but this PR adds symlink so that
"/usr/local/bin" still points to the nats-server.

Resolves #3239
