icecc: convert set_icecc_env to python prefuncs

Since bitbake commit f24bbaaddb36 ("data: Add support for new
BB_HASH_CODEPARSER_VALS for cache optimisation") the icecc fails with [1]:

ERROR: /Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb: no-pn NULL prefix
WARNING: /Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb: Exception during build_dependencies for set_icecc_env

The reason for this is the bb.fatal() within the icecc_version().
icecc_version() is called during the "${@}" python variable expansion
while bitbake is running the build_dependencies() for the
set_icecc_env() function.

To avoid this behaviour set_icecc_env() should be converted into a
python function which gets called during task[prefuncs] [2], which is
done by this commit.
