Fix spurious spaces in lsmod output

Browse Source 
While using "localyesconfig" to build a custom kernel I noticed that
lsmod output now has trailing spaces when the list of "Used by" modules
is empty.

The following patch just delays the space to the point where we are sure
that there are more things to print.
