[OE-core] [PATCH 1/9] icecc: Log reason in error cases

[Tobias Henkel]

From: Tobias Henkel <tobias.henkel at bmw-carit.de>

The current implementation doesn't give a hint about the cause in case
something went wrong in set_icecc_env. This makes it harder to find
out why a package is not being built using icecc. Therefore warnings
are inserted in the various error cases.
