icecc: use bb.utils.which also for 'as'

* it was introduced in
  commit 3a842ec52e7d010767b13bdcb5629ac07b3ee9e7

  Subject: icecc.bbclass: replace with updated version

  without any explanation in which case
    ${ICECC_CC} -print-prog-name=as
  is returning as in current working directory, but will keep old
  behavior just in case
