mysql_database: prevent syntax error with collate=>'binary'

On MySQL v5.5.38, creating a database such as:

	CREATE DATABASE `mydb` CHARACTER SET binary COLLATE binary;

seems to hit a parser bug. A workaround is simply to quote COLLATE
`binary`. As the quoting is harmless, and for aesthetics, quote both
the CHARACTER SET and COLLATE arguments.
