Remove deps from Sphinx.

Sphinx can use MySQL or PostgreSQL, and can use the mysql-connector libraries
instead of a full on MySQL install.

Since we don't know what datasource is intended, replace the hard dependency
with explanations in the caveats.

+    Sphinx depends on either MySQL or PostreSQL as a datasource.
+
+    You can install these with Homebrew with:
+      brew install mysql
+        For MySQL server.
+
+      brew install mysql-connector-c
+        For MySQL client libraries only.
+
+      brew install postgresql

+
+    We don't install these for you when you install this formula, as
+    we don't know which datasource you intend to use.
