fix the error in mac os while building psycopg2 from source

No need to build from source while psycopg2-binary already available.this fix most of the errors and unnecessary dependencies clashes happen when building from source.

Hi @charithmadhuranga, thank you for this PR. Can you please provide som more context about what errors you are seeing with the source build?

In general, the documentation of psycopg2 states the following:

The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.

So let's try to understand why you think this is necessary first.

hi freol35241, I was able to fix the error which cause at the integration installation time,by installing postgresql formula in homebrew before installing the ltss, brew install postgresql,this will install pkg_config ,psql as well as full postgresql server in the mac os ,which can be reduced if you are on development setup like me which simply using psycopg2-binary rather than the psycopg2.
