* libc/lseek.c: Modified after discussion with Eugeny S. Mints
	<jack@oktet.ru> to correct the behavior.  There were two mistakes.
	First, iop->offset was incorrectly set for SEEK_END.  Second,
	iop->offset should be left unmodified if there are errors.
	This modification attempts to fix both situations.
