paraview: package hydra_pmi_proxy into `bin` as well
this iwas working perfectly (5.2 5.3 identical) :
ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin]$ LD_LIBRARY_PATH=../lib ../lib/paraview-5.3/mpiexec -np 2 ./pvserver
Waiting for client...
Connection URL: cs://snowman:11111
Accepting connection(s): snowman:11111
While this was not (note the path to mpiexec) :
ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin]$ LD_LIBRARY_PATH=../lib ./mpiexec -np 2 ./pvserver
[mpiexec@snowman] HYDU_create_process (utils/launch/launch.c:75): execvp error on file /home/glow/work/kitware/paraview/other/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin/./hydra_pmi_proxy (No such file or directory)

the provided mpiexec in bin was not packaging hydra_pmi_proxy correctly, this fixes it
