terminal-encoding: Remove -Wformat warning

[rbuj]

Test

$ ./autogen.sh --prefix=/usr --enable-compile-warnings=maximum --enable-debug && make &> make.log
$ grep -A 2 Wformat make.log 

Removed warnings

terminal-encoding.c:251:27: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘gsize’ {aka ‘long unsigned int’} [-Wformat=]
  251 |                           " output \"%s\" bytes read %u written %u\n",
      |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Aha, the parameter --debug is needed to see the warning. For that reason you won't find the warning at current travis build from master.

Well, technically, since it's like a size_t, we need different modifiers for 32-bit and 64-bit systems. The manual tells there are G_GSIZE_MODIFIER and/or G_GSIZE_FORMAT: https://developer.gnome.org/glib/stable/glib-Basic-Types.html#gsize

(check these macros in /usr/lib/.../glib-2.0/include/glibconfig.h for the actual values)

@monsta done.
