[OSS-Tools] [PATCH dt-utils] meson: align libdt-utils version with autotools'

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Makefile.am has:

  LIBDT_CURRENT=6
  LIBDT_REVISION=0
  LIBDT_AGE=0

along with a comment on how the values were chosen. Copy the comment and
the values into the meson.build as well, so appropriate symlinks
pointing at the versioned library are created. We forego the extra
complexity of having a common file that's read from both build systems
as we are intent on phasing out autotools anyway, once wrinkles such as
what's fixed here are ironed out.
