Gunar Schorcht cbbd02d520 dist/tools: rename esptool to esptools to use it for several tools
The directory `dist/tools/esptool` already contains a couple of ESP tools and not only esptool.py. As the location for a couple of ESP related tools, it is more clear to call it `esptools` instead of `esptool`.
