Ensure wpa_supplicant logs to syslog

Description

After enabling encryption as described in the documentation I noticed that every so often the DECRYPT_ME hotspot is not started.

Motivation and Context

Currently wpa_supplicant does not log to its own file or syslog so this issue is hard to pin down. Having wpa_supplicant log to syslog allows for some troubleshooting

• I have raised an issue to propose this change (required)

#1055

How Has This Been Tested?

Manually updated wpa_supplicant command in pwnlib with additional flags (-u -s -O) and rebooted. wpa_supplicant now logs to syslog.
