net/endlessh/Makefile needs ${STRIP_CMD} instead of ${STRIP} or poudriere builder involved can hang during post-install ( running ${STAGEDIR}${PREFIX}/bin/endlessh )

My experimental "poudriere bulk -a -c" had its net/endlessh
build hang up because it ran ${STAGEDIR}${PREFIX}/bin/endlessh
during staging's post-install target, ${STRIP} was empty.

In other words, something like the below is needed:
(some whitespace details might not survive email and such)

# git -C /usr/ports diff /usr/ports/net/endlessh
diff --git a/net/endlessh/Makefile b/net/endlessh/Makefile
