[Box Backup-dev] bin vs sbin

[James O'Gorman]

I'm just going over the manpages as I've noticed some of the sections
seem to be incorrect, and just thought - currently we put everything in
$prefix/bin.

Should we move the "system" commands to $prefix/sbin? By this I mean:

 * bbackupd
 * bbackupctl
 * bbackupd-config
 * bbstored
 * bbstoreaccounts
 * bbstored-certs
 * bbstored-config

bbackupquery seems to be the only "user" command that we actually have.
If everyone agrees with this, is it just a case of editing modules.txt?
