sort: remove duplication from usage string

Browse source 
The custom usage string does not have to include the "sort\nUsage:" part,
because this part is already printed by clap.

It prevents the following duplication:

USAGE:
    sort
Usage:
 sort [OPTION]... [FILE]..

Now, only the following is printed:

USAGE:
    sort [OPTION]... [FILE]...
