[tex-live] fontspec for LuaTeX

In my test on windows, mkluatexfontdb failed at

otfl-font-nms.lua:487: attempt to index local 'path' (a nil value)

line 486 is
        path = kpse.readable_file(path)

Note that kpse.readable_file(path) returns a nil value if
path is a directory. In my case the path was a directory
"destdir" for the command line:

mkluatexfontdb --database-dir=destdir

Thanks,
Akira
