can't build master: es_poll_t type is unknown in common/sh-exectool.{c, h}

[Daniel Kahn Gillmor]

i can't build from the current master because of errors having to do
with es_poll_t in common/sh-exectool.{c,h}, which seems to have been
introduced without any declaration of the type in
2ae07f826aa551db8adf714158fce962790a6b54 and
a81aca6e1c2a4529d416d1989f15d7338d2ee81e.

for example:
