create a pkg-config package for Flux PMI #921

This PR adds a pkg-config package for Flux's in support of an OpenMPI "flux" component under discussion in rhc54/ompi#1. is purposefully excluded from flux-core's pkg-config package because in general we want the selection of a PMI library to be a runtime decision. The new component will normally try to dlopen our library at $FLUX_PMI_LIBRARY_PATH. However in cases where OpenMPI builds all its modules statically (apparently common on big systems), dlopen is not permitted and it needs to find our at build time. Using pkg-config for this avoids hard wiring a search heuristic in the configuration m4sh for the flux component.

Unrelated fix to a silly output typo in a PMI test program is tacked on here as well.

build: add flux-pmi.pc
Add a pkg-config file for that allows a future
openmpi mca for flux to link against it without complex
autoconf m4.

The mca in development dlopens the library path from
FLUX_PMI_LIBRARY_PATH environment variable by default,
but may be built against a specific Flux library path
in the case where openmpi is being built with --enable-static
or --disable-dlopen, apparently common on large clusters.

Discussed in rhc54/ompi#1
test/pmi: fix time units output by kvstest
Problem: kvstest output reported time in seconds, but
the time is from monotime_since() which is in milliseconds.

Change sec to msec in the output.
