1. libflux/conf: add bindir attribute …

   Problem: we need a way to determine the directory
   where the flux command front end is built.
   
   Add 'bindir' conf attribute for
      in tree:    ${abs_top_builddir}/src/cmd
      installed:  ${prefix}/bin
   
   Access with flux_conf_get ("bindir", flags).

2. cmd/flux: reverse logic of in-tree detection …

   Problem: when flux is launched by spindle, /proc/self/exe
   no longer refers to $prefix/bindir and flux attempts
   to use paths relative to its build directory to access
   the rest of flux.
   
   Instead of comparing /proc/self/exe's symlink target
   to $prefix/bindir, compare to ${abs_top_builddir}/src/cmd.
   That way the installed executable can be relocated
   without harm, and the "special" case is the one where
   flux is run out of the build tree, which seems appropriate.
   
   The problem launching flux with spindle is discussed
   in issue flux-framework#1514.
