ed: align output of read command with POSIX.1-2008

POSIX.1-2008 mandates the following regarding the read command:

	If the read is successful, and -s was not specified, the number
	of bytes read shall be written to standard output in the
	following format:

	    "%d\n", <number of bytes read>

This commit aligns the output of busybox ed with POSIX.1-2008 by
removing the file name from the output for the read command.

This slipped through in 4836a0708fd0aaeb82871a3762b40fcf4b61e812.
