    [gdb/testsuite] Fix gdb.base/maint.exp on powerpc64le
    
    On powerpc64le-linux, I ran into:
    ...
    FAIL: gdb.base/maint.exp: maint print objfiles: symtabs
    ...
    
    The problem is that:
    - the "Cooked index in use" line occurs twice in the gdb output:
      - once for exec maint, and
      - once for "Object file system-supplied DSO".
    - the matching of the second "Cooked index in use" also consumes
      the "Symtabs:" string, and consequently the corresponding
      clause does not trigger and $symtabs remains 0.
    
    Fix this by limiting the output of the command to the exec.
    
    Tested on x86_64-linux and powerpcle-linux.
