[pkg-go] Bug#840031: gobgp: FTBFS (32-bit): constant 4294967295 overflows int

[Aaron M. Ucko]

Source: gobgp
Version: 1.12-1
Severity: important
Justification: fails to build from source

Builds of gobgp for 32-bit architectures are doing better now that
you've addressed #836805 (thanks!), but still ultimately fail:

  # github.com/osrg/gobgp/table
  src/github.com/osrg/gobgp/table/policy_test.go:2338: constant 4294967295 overflows int
  FAIL	github.com/osrg/gobgp/table [build failed]

Could you please take a look?

Thanks!
