Regression test instructions not working

[tiziano88]

I am following the instructions in

asylo/README.md

Lines 160 to 181 in 5ab253e

	#### Running the regression tests
	To run our regression test suite, first clone the Asylo repository to a
	directory of your choice.
	```bash
	ASYLO_SDK=~/asylo-sdk
	git clone https://github.com/google/asylo.git "${ASYLO_SDK}"
	```
	The regression test suite includes tests that unit-test code directly as well as
	tests that run inside a simulated enclave environment. You can run it with the
	following command:
	```bash
	docker run -it --rm \
	-v "${ASYLO_SDK}:/opt/asylo/sdk" \
	-v bazel-cache:/root/.cache/bazel \
	-w "/opt/asylo/sdk" \
	gcr.io/asylo-framework/asylo \
	asylo/test/run_enclave_tests.sh
	```

but getting the following errors:

@tiziano88, can you some more information on what steps you performed?

Running from HEAD with the current docker container image builds/passes fine for me. Could you try docker pull gcr.io/asylo-framework/asylo to make sure you don't have an old version? What commit/tag are you using?

The first error in your output seems to be a legit issue (we removed a file, but didn't delete it from the exports_files in the BUILD file). I'll make sure we get that fixed, but I'm not seeing it result in build errors (is it possible your example BUILD file refers to the non-existent asylo/bazel/proto.bzl?).

It also seems some of your errors may be related to content you added to "asylo/examples/bazel-my-project", but I can't be sure without seeing what's there.
