a few minor kldstat fixes

[Alexander Best]

this patch fixes the following issues:

- unbreak 'kldstat -i 999 -v' output
- remove an unnecessary set of "{" and "}"
- change printfile() to blend into the overall style used in kldstat.c
- add a kldstat(8) entry to document the relationship between the "-i" and "-n" flags

cheers.
