aubdump: Handle 48-bit relocations properly

aubdump was only writing 32-bits regardless of platform.  This is fine if
the client being dumped leaves the top 32 bits zero since the aubdump GTT
is fairly small.  However, if the client does store something in the upper
32 bits, this results in an invalid relocation.
