[1.7.x] Fixed #22626 -- Allow BinaryField defaults with SQlite.

Also fixes a slight issue in sqlite3.schema._remake_table where
default values where quoted with "column name" quoting rules.

Reference for quoting: http://www.sqlite.org/lang_expr.html

Thanks Shai Berger for the review. Refs #22424.
