Use OWNERS filters to give approval to ixdy for Bazel build changes

**What this PR does / why we need it**: Bazel updates tend to affect a bunch of `BUILD` files throughout the tree. Rather than getting @thockin to rubber-stamp these all the time, give me the power to approve? I already have appoval over `build/` and `hack/`, which is related to these files.

Happy to add other owners here too, though I don't know who else wants to own.

Previously: https://github.com/kubernetes/kubernetes/pull/45245, https://github.com/kubernetes/kubernetes/pull/45855

**Release note**:
