package/libevdev: convert to meson

- drop legacy patch 0001-configure-add-disable-runtime-tests-option.patch
  and use -Dtests=disabled instead

- drop host-pkgconf dependency as pkgconf is only used in case tests
  are enabled to find the check package (checked via meson output -
  no 'Found pkg-config' - and via strace)

- update host-python dependency to host-python3 as the script
  libevdev/make-event-names.py which is used to generate the
  header file event-names.h is updated to python3:
  '#!/usr/bin/env python3'
  This made no difference with autotools build as the script
  was called with '$(PYTHON) libevdev/make-event-names.py'.

  We use BR2_PYTHON3_HOST_DEPENDENCY instead of depending on
  host-python3, to use any available Python 3.x interpreter on the
  build machine instead of building our own, if possible.

- add patch to fix tools compile with older toolchains adding
  the local include path (only the meson build is affected)
