Fix off-by-one in buffer_size usage
The added null byte was accounted for twice, once by taking opt.buffer_size+1 when allocating the buffer and once by taking opt.buffer-1 when filling the buffer. Make opt.buffer_size the size that is actually read, it's less confusing that way. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
