libgpiod: update to 2.1.3

Upstream bug fixes:
- fix C++ tests with recent kernels which introduced stricter reconfigure
  behavior
- fix a use-after-free bug in python bindings
- fix passing the event clock property to line requests in python bindings
- fix a memory leak in tools
- make sure the string buffers in line-info and chip-info are big enough to not
  truncate the strings they hold below the size accepted by the kernel
