google-protobuf and grpc gems fail #86
Description
When trying to use google-protobuf and grpc gems, the paths created do not match the globs in the generated BUILD.bazel file.
For example, here's the library rule generated for grpc:
ruby_library(
name = "grpc",
srcs = glob(
include = [
".bundle/config",
"lib/ruby/2.7.0/gems/grpc-1.35.0/lib/**/*",
"lib/ruby/2.7.0/specifications/grpc-1.35.0.gemspec",
],
exclude = ["**/* *.*", "**/* */*"],
),
deps = [":google-protobuf", ":googleapis-common-protos-types"],
includes = ["lib/ruby/2.7.0/gems/grpc-1.35.0/lib"],
)The glob in the srcs attr does not match any of the files, as both the gem name and contents are possibly incorrect.
In grpc's case, the path is lib/ruby/2.7.0/gems/grpc-1.35.0-x86_64-linux/... and does not contain a 'lib' directory.
In google-protobuf's case, the path is lib/ruby/2.7.0/gems/google-protobuf-3.14.0-x86_64-linux/... and does contain a 'lib' directory.
Therefore, when trying to require 'grpc' it cannot find any files:
/usr/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require': cannot load such file -- grpc (LoadError)
Context: rules-proto-grpc/rules_proto_grpc#65

This is a known limitation.
When adding gems we were hard coding the lib folder. The PR submitted by @mmizutani should fix it.

Cycling back around to this: grpc still fails to load due to missing a file at
etc/roots.pem. It's a pretty odd layout that can be fixed by addingincludes = {"grpc": ["etc"]}to theruby_bundlecall, but I dunno if there's a fix you want to do here for that?
