Tweak if This Script is Renamed

In programs like ConEmu, very often users want to pass their own options
into Clink. This involves replacing clink.bat with their own custom one,
which will then call the original clink.bat with a new name. This tweak
keeps the original behavior of looking for clinkXXX_x64.exe when the
batch script is named clinkXXX.bat, but provides a fallback for it to
run clink_x64.exe if clinkXXX_x64.exe cannot be found.
