[mdatagen] bugfix: fix generated package test when skipping goleak, because os package import is forgotten

[Arthur1]

Description

When tests.goleak.skip flag is set to true, the generated_package_test.go file looks like the following image.

Since import os statement is missing, you fail to run the test. I added the missing import in this PR.

Testing

Compare the generated generated_package_test.go when tests.goleak.skip flag is toggle from false to true.
