I'm an idiot. :-(

We need to do something in drivers/main.c as well, to make sure 'progname'
contains something useful before calling upsdrv_banner(). I have probably
not fully recuperated from my business trip to Chicago last week.

I'll commit this change to drivers/main.c later today. It might be useful
to know the program name at that time anyway, even without softlinks to
replace obsolete drivers silently.
