tio: update to 1.37.

=== tio v1.37 ===

Changes since tio v1.36:

* Make libinih a fallback dependency

  This means that in case meson does not find libinih it will
  automatically clone libinih and include it in the build.

  The libinih library is reconfigured to be statically built so that no
  shared object will be installed.

Sylvain LAFRASSE:

* Fix timestamp parsing in INI conf

* Factorize timestamp parsing to be coherent with command line format in
  configuration file.
