Make sure bin/run script finds the correct dlls

On Windows/Cygwin, if you put "C:\Program Files\LibreOffice\program"
in PATH, bin/run will have trouble finding correct vcllo.dll and other
LibreOffice .dll files inside instdir/program. Because the script uses
the absolute path of the executable, it is enough to use instdir/program
as the current working directory.

The symptom was that in the above case it was not possible to run the
workbenches like vcldemo, minvcl, etc. The error was:

$ ./bin/run minvcl

minvcl.exe - Entry Point Not Found | The procedure entry point
?RasterFromBitmap@SKImages@@... could not be located in the dynamic
link library vcllo.dll

$ ldd ./lode/dev/core/workdir/LinkTarget/Executable/minvcl.exe
...
comphelper.dll => not found
fwklo.dll => not found
