[PATCH] Allow override of phonesim conf

Hi

Currently phonesim tries to open its conf file from the location 
specified at configure time (/etc/ofono/phonesim.conf). For testing 
purposes it would be nice to be able to override this. This patch allows 
you to override the location with the environment variable 
OFONO_PHONESIM_CONFIG.

Thanks,
