I think the reason of the failure may be the newer
version number of included PDF files.
In TL'15, xdvipdfmx also checks the version number
as dvipdfmx. Try

xetex --output-driver="xdivpdfmx -V 7 -q" foo.tex

or

xelatex --output-driver="xdivpdfmx -V 7 -q" foo.tex

If you want to set the PDF 1.7 as a default,
change the line 13 of $TEXMFDIST/dvipdfmx/dvipdfmx.cfg
from

V  5

to

V  7

Thanks,
Akira
