Subject: [PATCH AUTOSEL 4.19 35/68] tc-testing: tdc.py: ignore errors when decoding stdout/stderr

From: Lucas Bates <lucasb@...atatu.com>

[ Upstream commit 5aaf6428526bcad98d6f51f2f679c919bb75d7e9 ]

Prevent exceptions from being raised while decoding output
from an executed command. There is no impact on tdc's
execution and the verify command phase would fail the pattern
match.
