[core 4/6] log: rename the environment variable to GRL_DEBUG

[Víctor Manuel Jáquez Leal <vjaquez igalia com>]

From: Damien Lespiau <damien lespiau intel com>

The log system uses an environment variable to override the verbosity of
log domains. Let's use GRL_DEBUG to be closer to what other gnome
libraries use (GST_DEBUG, GTK_DEBUG, CLUTTER_DEBUG).
