[PATCH] config: verify that the config file has been parsed

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

weston_config_parse may return NULL, leading
to an ungraceful exit via SIGSEGV.

Adding a nice check that gracefully exits the compositor
when the config.ini parsing failed.
