Unable to override file by machine for phosphor-ipmi-fru-properties

[Patrick Venture]

With phosphor-ipmi-fru-properties, if we set the
FILESEXTRAPATHS_prepend to be machine specific, it can't find the file
and doesn't add the path, but if we leave off the machine override,
it'll find the file and use it.

https://github.com/openbmc/meta-ingrasys/blob/master/meta-zaius/recipes-phosphor/ipmi/phosphor-ipmi-fru-properties%25.bbappend

This specifies that for zaius, it should prepend with this path and
use this override file.

Deleted the extra-properties.yaml file from the original recipe and
tried building zaius:

Ok, it can't find it.  But when I delete the machine override on the
line, basically delete "zaius" it then finds the file and uses the
zaius file correctly.  This behavior is baffling me, does anybody have
any ideas?  Has anyone seen this behavior?
