Make it so view doesn't depend on setup

From a recent discussion in Slack (internal), running make view also runs the setup step which invokes asdf to install the dependencies. The thing is that asdf also picks the parent directory's .tool-versions in which GDK resides. This led to some errors while trying to build postgres:

relpath.c:21:10: fatal error: 'catalog/pg_tablespace_d.h' file not found

Since the setup instructions are pretty comprehensive, we don't really need to run setup when running view.
