getting-symbiflow.rst: Clarified download location

Clarifies that the conda_installer.sh script should be downloaded into
the git repository.

By habit, I place downloaded scripts into the ~/Downloads directory, and
avoid adding non-repo files to repositories. However, when I did that I
ended up with some difficult to diagnose bugs several steps later. It
was only on carefully rereading the instructions I realized what I ought
to have done. The intention of this change is to make clear to other new
users that they ought to place conda_installer.sh into the git repo
directory.
