install modules all at once

build an array of paths to modules, and install them all at once with
mkdir -p and cp --parents. Cuts back on our major source of calls to
install(1).

This is a tad ugly in that it creates some amount of data duplication,
keeping an array of paths in addition to module names. However, turns
out to be a worthwhile tradeoff as merging the two datasets into one
results in the need for massive string trimming.
