improve build:ssr by passing max_old_space_size to ng run command

This PR extends the heap space adjustment in build:ssr to the second ng run comannd.

We have seen reproducable out-of-memory error when building the Docker image. The error occurs after the successful completion of the first command in build:ssr (which is already adjusted in terms of available heap space).

Output when running docker build:
