[tex-live] tlmgr conf does not report xetex/luatex paths

[Nelson H. F. Beebe]

Jean-François asks about adding xetex and luatex to the executables
tested for by "tlmgr conf".

If that change is made, let's do one more thing: line up the output
in neat columns for better visibility:  compare these two reports:

%  tlmgr conf | grep /bin

Readability matters!
