[gold] PATCH: Correct relocation offset

["H.J. Lu" <hongjiu.lu@intel.com>]

Hi,

The layout of .gnu_incremental_relocs section entry is

4byte: r_type
4byte: out_shndx
addr_size: offset
addr_size: addend

and incremental.cc uses

8 + 2 * parameters->target().get_size() / 8;

or

8 + 2 * sizeof_add

to compute .gnu_incremental_relocs entry size.  However,
write_info_blocks uses "3 * sizeof_addr", which only works for 64bit
target.  This patch fixes it.  OK to install?

Thanks.
