smbtorture: Allow debugging output to be configured using smb.conf parameters

smbtorture: Allow debugging output to be configured using smb.conf parameters

It might be useful to see timestamps for some smbtorture tests.

Timestamps can be printed via 'debug syslog format=always'.
It can be specified either in smb.conf or directly via smbtorture option
-T 'OPTION=VALUE'     smb.conf option line

However, smbtorture is not evaluating the option. It needs to call
reopen_logs()->debug_set_settings() to copy
'Globals.debug_syslog_format' to 'state->settings.debug_syslog_format'

$ bin/smbtorture3 //foo/bar -U% LOCAL-G-LOCK4 -d10 -T 'debug syslog format=always'
