[virt-tools-list] [virt-viewer] Use the same debug log handler regardless of glib version

[Christophe Fergeau]

Commit 2bd835fb introduced a custom log handler to ensure
we never show debug messages by default regardless of glib
version (older glib were showing them by default).
These messages are only shown if the global variable 'doDebug'
is set (ie when virt-viewer is started with --debug).

This special log handling is only performed with older glib versions.
However, virt_viewer_app_set_debug() also has some code used with newer
glib version to make sure debug messages are displayed  when using
--debug.

Using the custom log handler regardless of the glib version allows to
get rid of this version-specific code (and avoids a bug with
glib_check_version() with the current code, the check for
glib_check_version() return value is inverted).
---
The discussions around 'util: fix glib_check_version() condition' made me
realize that we probably don't need the glib version check at all
(only tested with glib 2.40)
