altmbr: cap at 439 bytes so the partition select byte follows
Cap altmbr at 439 bytes, so that the partition select byte is not part
of the file. This means that:
a) updating the altmbr doesn't clobber the configuration;
b) it is easier to simply concatenate the select byte to the file.
This also matches gptmbr behavior.
