flux-core, flux-sched: add 0.29.0, 0.18.0 and cleanup env vars (#26391)

Problem: Flux expects the `FLUX_PMI_LIBRARY_PATH` to point directly at
the `libpmi.so` installed by Flux.  When the env var is unset,
prepending to it results in this behavior.  In the rare case that the
env var is already set, then the spack `libpmi.so` gets prepended with a
`:`, which Flux then attempts to interpret as a single path.

Solution: don't prepend to the path, instead set the path to point to
the `libpmi.so` (which will be undone when Flux is unloaded).

* flux-core: remove deprecated environment variables

The earliest checksummed version in this package is 0.15.0. As of
0.12.0, wreck (and its associated paths) no longer exist in Flux. As of
0.13.0, the `FLUX_RCX_PATH` variables are no longer used. So clean up
these env vars from the `setup_run_environment`.
