builtin/commit-graph.c: remove subcommand-less usage string

The first line in 'git commit-graph's usage string indicates that this
command can be invoked without specifying a subcommand.  However, this
is not the case:

  $ git commit-graph
  usage: git commit-graph [--object-dir <objdir>]
     or: git commit-graph read [--object-dir <objdir>]
  [...]
  $ echo $?
  129

Remove this line from the usage string.

The synopsis in the manpage doesn't contain this line.
