Update and improve gVisor support: - Implement event handlers for recently-added gVisor native events, including WRITE - Enhance event handlers to explicitly document which SCAP event fields are invalid (e.g. where info is not provided by the native gVisor event) - Improve gvisor config generator, to configure all fields needed by the event parser, and only those fields - Zero fill allocated scap_gvisor_platform structure, to avoid crash on startup - Return SCAP_TIMEOUT instead of SCAP_EOF on interrupted socket read - Add new gvisor parser unit tests for new event handlers; and fix existing unit tests to reflect updated functionality of existing event handlers Signed-off-by: Joseph Pittman <joseph.pittman@sysdig.com>

update(userspace/libsinsp): remove deprecated=true from cri.proto The deprecation annotation produced warnings when building. Since the warning is not really relevant to libs code and might be problematic for dependant projects (especially when a project uses warnings as errors, like Falco), we are just suppressing it by removing the annotation.

Partially automate cri.proto handling musl libc defines stdin, stdout and stderr as macros, so the names cannot be used as field/method names in generated CRI protobuf code. Before this change, we patched cri.proto with a static patch, which is tedious while upgrading cri.proto. Introduce a script, `userspace/libsinsp/scripts/update-cri-proto`, that downloads the latest version, replaces the problematic names and saves a new version of `userspace/libsinsp/cri.proto`. Note: this script requires bash and possibly GNU sed. Note 2: we also replace some occurrences of stdin/out/err in the comments, which looks weird but is harmless.
