wpa_supplicant: Fix ctrl_interface group permissions to allow read/execute
When using umask 0077, the control interface directory was left without
group read/execute permissions even if the configuration file explicitly
asked for the group to be allowed to access the control interface. Fix
this by adding read/execute permissions for group if a specific group is
defined in the configuration. [Bug 199]
