gdb/memdump: add option to exclude nodes from specific PID

Browse source 
This is useful to exclude memory nodes for mempool.

E.g.

(gdb) mm dump --nob --top 5 --sort size --nop --no-pid -1
  Pool          CNT          PID         Size  Overhead          Seqno            Address Backtrace
     H            1            0     16777264        44             13         0x41a79010
