[OE-core] [thud][PATCH] icecc-env: don't raise error when icecc not installed

[Adam Trhon]

When icecc is not installed, the `which icecc` command in icecc-env.sh
returns nonzero. This happens when environment is being sourced. When
the terminal has `set -e`, the whole script fails and terminal is
closed.

Fix this by ignoring errors from the which command.
