[BF] bird2: Remove stray whitespace when no MD5

When no MD5 password is set, there should not be extra whitespace.

This is a minor thing right now, but its something that intersects with other changes I made for BFD.

Please verify the output before merging. This works on my system, but I have another line added after it in my skin. Also, I do not run a route collector, so the change there has not been tested.

In addition to the above, I have:

• ensured all relevant template output is escaped to avoid XSS attached with <?= $t->ee( $data ) ?> or equivalent.
• ensured appropriate checks against user privilege / resources accessed
• API calls (particular for add/edit/delete/toggle) are not implemented with GET and use CSRF tokens to avoid CSRF attacks

BTW, even if you don't care about BFD upstream, I would still appreciate if this change could be merged, as it makes it easier for me to skin in BFD.

@rlaager - yes, I'll look at merging this. We're super sensitive about anything that touches router configuration and especially route server configuration as those are production critical services.

This means generally that merges have to be covered by the test database and by the sample known good configs; and that they have to apply cleanly without interrupting BGP sessions.

At a glance, the no-md5 use case is either not covered by the configs / test cases and so I'll need to add that in.
