build: run-ci makefile rule

Adding a single rule to be called from Jenkins.

Jenkins jobs typically call:
python ./configure
make -j $(getconf _NPROCESSORS_ONLN)
make test-ci

After this change, we can have Jenkins call:
make run-ci -j $(getconf _NPROCESSORS_ONLN)

This allows us to customize how we call configure
for different repos or branches (e.g. joyent\node).
