Some tests are using logs to validate that a test behaves correctly
however they used `platform shell cat {log}` to read the logfile.
This doesn't work when running the testsuite against a remote platform
since the logs are saved on the host's filesystem.
This patch addresses those failures by making sure we read the log file
from the host platform.
