Refactor //library/rocksdbjni: replace 'make' in favour of '@rules_foreign_cc'

[lolski]

We found a Bazel rule @rules_foreign_cc [link] which allows for building make projects from inside a Bazel workspace. We should replace our builder script RocksDbBuilder.kt with this rule if possible

I couldn't get it to work on the first try, but the Bazel WORKSPACE and BUILD files would roughly look like this, according to the @rules_foreign_cc's README:

# WORKSPACE

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
files = """filegroup(name = "all", srcs = glob(["**"]), visibility = ["//visibility:public"])"""

http_archive(
   name = "rules_foreign_cc",
   strip_prefix = "rules_foreign_cc-master",
   url = "https://github.com/bazelbuild/rules_foreign_cc/archive/master.zip",
)
load("@rules_foreign_cc//:workspace_definitions.bzl", "rules_foreign_cc_dependencies")
rules_foreign_cc_dependencies()

http_archive(
   name = "rocksdbjni_dev",
   build_file_content = files,
   strip_prefix = "rocksdb-6.11.4",
   urls = ["https://github.com/facebook/rocksdb/archive/v6.11.4.tar.gz"],
)

# BUILD

load("@rules_foreign_cc//tools/build_defs:cmake.bzl", "cmake_external")

cmake_external(
   name = "rocksdbjni-dev",
   lib_source = "@rocksdbjni_dev//:all",
)

And here's how you would actually trigger the make compilation

bazel build //library/rocksdbjni:rocksdbjni-dev
