[PATCH] Improve load command's help text

[Luis Machado <lgustavo@codesourcery.com>]

This fairly obvious patch adds usage text to the load command's help text.

Originally it did not have usage and mentioned things like FILE and OFFSET
without explaining how those should be passed in the command.

	* symfile (_initialize_symfile): Add usage text to the load command's
	help text.
