Redirect from install.php to core/install.php

Help Drupal 7 folks who are used to the old path.

Per Josh, we are not going to try to solve problems that Drupal core is not solving. Since the "Drupal 8" way is to go directly to core/install.php on reinstall, that is what we will require on Pantheon as well.

We might want to revisit this decision, as Drupal 8 core now does this redirect as a service:

  # Redirect common PHP files to their new locations.
  RewriteCond %{REQUEST_URI} ^(.*)?/(install.php) [OR]
  RewriteCond %{REQUEST_URI} ^(.*)?/(rebuild.php)
  RewriteCond %{REQUEST_URI} !core
  RewriteRule ^ %1/core/%2 [L,QSA,R=301]

Most folks won't try to go directly to the old location, so this is something of an edge case; downgrading to 'enhancement'.
