[PATCH openbmc v3 7/9] obmc-phosphor-image: Improper use of DATETIME

[OpenBMC Patches]

From: Patrick Williams <patrick at stwcx.xyz>

The use of the DATETIME variable has issues with the sstate cache
because of the variable changing values, and therefore the checksum
used for sstate calculation also changing.

Other existing recipes add DATETIME to the 'vardepsexclude' list.
This case is glossed over very rapidly in section 21.3.2 "Checksums"
of the Mega Manual.
