[OE-core] [PATCH 2/2] image.bbclass: improve reproducibility

[Burton, Ross]

I think this is to blame for a slew of failures on the autobuilder:

http://errors.yoctoproject.org/Errors/Latest/?filter=57ddf212e64207edfbd813d32ca3a15f6c1c8211&type=commit

Such as:

NOTE: FAIL [0.616s]: test_df (df.DfTest)
NOTE: ----------------------------------------------------------------------
NOTE: Traceback (most recent call last):
