Comparing logs, the older LuaTeX version executes
repstopdf --outfile=mwe-eps-converted-to.pdf mwe.eps
while the newer one executes
epstopdf --outfile=mwe-eps-converted-to.pdf mwe.eps
see the parallel thread re status.shell_escape on this list,
anything doing a status check on shell escape will be broken in the current
tl2017 test release.
