lib/igt_core: Handle glib errors correctly to avoid stderr spew

This adds the required error clean/free calls after calling
configuration parsing functions. In addition to properly handling memory,
this avoids glib spewing out error messages on stderr, which breaks the
whole CI with this message:

    GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
    This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
    The overwriting error message was: Key file does not have group ?DUT?

Fixes: ee31e0b5 ("Introduce common frame dumping configuration...")
