build/toolchain/protobuf: fix duplicate protoc build

We were building way too many copies of protoc. Many of these are due to
a bug in rules_go when --incompatible_enable_proto_toolchain_resolution
is enabled, but not all, so we should do this anyway, and then the bug
in rules_go is no longer relevant.

Before:
bazel cquery "deps(//...) intersect @protobuf//:protoc"
@protobuf//:protoc (e5c4511)
@protobuf//:protoc (40d0309)
@protobuf//:protoc (3bbe29a)
@protobuf//:protoc (070fbf5)
@protobuf//:protoc (ee343a7)
@protobuf//:protoc (c3e4ff6)

After:
bazel cquery "deps(//... except //build/toolchain/protobuf/...) intersect @protobuf//:protoc"
@protobuf//:protoc (ee343a7)
