Update rules_cc

The previous version does not mark the `toolchain_type` as public,
meaning that users of a CC toolchain using
`@rules_cc//cc:toolchain_type` will get build errors along the lines of
```
ERROR:
.../local_config_cc_toolchains/BUILD.bazel:18:1:
in toolchain rule
@local_config_cc_toolchains//:cc-toolchain-armeabi-v7a: alias
'@rules_cc//cc:toolchain_type' referring to target
'@bazel_tools//tools/cpp:toolchain_type' is not visible from target
'@local_config_cc_toolchains//:cc-toolchain-armeabi-v7a'. Check the
visibility declaration of the former target if you think the dependency
is legitimate
```
