[pkg-go] Bug#1013350: Update vuls dependency to bbolt

[Ileana Dumitrescu]

Package: vuls
Version: 0.7.0-1
Tags: FTBFS upstream

vuls FTBFS for riscv because of its dependency on golang-github-boltdb-bolt, which is outdated and incompatible with riscv. The upstream should update the dependency from golang-github-boltdb-bolt to golang-github-coreos-bbolt, which is an updated fork of bolt with riscv support. Full build log at [0].
