Update sqlite, taglib, and wand for new 'magic:*' defuns.

This updates a few things to use the new and improved ffi-magic.

	* lisp/ffi/ffi-sqlite.el (sqlite-file-p): Use #'magic:file to get
	the job done.

	* lisp/ffi/ffi-wand.el (Wand-file-supported-for-read-p):
	Use #'magic:file-image-p to test file type.

	* lisp/ffi/ffi-taglib.el (taglib:mimetypes): New, replaces
	`taglib:extensions'
	(taglib:extensions): Removed.
	(taglib:get-tag): Use #'magic:file to test for supported file
	formats.
	(taglib:list-all-tags): Ditto.
