Subject: [PATCH] Guard FORCE_NODE_VERSION in the version error path (#7983)

Installing on the wrong node version dies with "FORCE_NODE_VERSION: unbound
variable" instead of explaining itself. The script runs under set -u and
this is the one place the variable is read bare; the three other reads all
default it.
