[yocto] [prelink-cross] [PATCH] testsuite/functions.sh: produce deterministic GNU_PRELINK section

[Sergei Trofimovich]

Before the change one test failed due to timestamp drift:
  FAIL: shuffle7.sh

This happens because prelinking takes time on the file
and timestamp differs slightly.

Avoid timestamp drift by overriding real timestamp
with PRELINK_TIMESTAMP variable.
