Harmonize spacing after ellipses in install.sub

[Frederic Cambus]

Hi tech@,

We are using spacing after ellipses in displayed messages in an
inconsistant way.

A few examples:

- openssl: generating isakmpd/iked RSA keys... done.
- syncing disks... done
- iwm0: no link ..... got link
- iwm0: no lease ...... got lease

Another example, from syspatch:

- Relinking to create unique kernel... done.

In install.sub though, we find the same message for kernel relinking,
without a space this time:

- Relinking to create unique kernel...done.

And most messages with ellipses in install.sub are displayed without a
space, except for:

- Checking for available binary patches... done.

I propose to standardize on using "... " everywhere, and the following
diff enforces this for the installer.

Comments? OK?
