[posix] use default when passing nullptr to SettingsFile::SetSettingsPath (#12268)

Browse Source 
This commit adds the nullptr check in `SettingsFile::SetSettingsPath`.
If the nullptr is passed to `SettingsFile::SetSettingsPath`, it will
set the settings path to a default path
(OPENTHREAD_CONFIG_POSIX_SETTINGS_PATH).
