[OE-core] [sumo][PATCH 1/7] icecc-create-env: Allow logging to a file

[Joshua Watt]

Modifies the icecc-create-env script so that it can log output to a log
file. In addition, a --debug flag is added that allows verbose logging.
Finally, the silent flag was removed since it was never used in
icecc.bbclass
