Quentin Monnet 54b66c2255 tools, bpftool: Fix variable shadowing in emit_obj_refs_json()
Building bpftool yields the following complaint:

    pids.c: In function 'emit_obj_refs_json':
    pids.c:175:80: warning: declaration of 'json_wtr' shadows a global declaration [-Wshadow]
      175 | void emit_obj_refs_json(struct obj_refs_table *table, __u32 id, json_writer_t *json_wtr)
          |                                                                 ~~~~~~~~~~~~~~~^~~~~~~~
    In file included from pids.c:11:
    main.h:141:23: note: shadowed declaration is here
      141 | extern json_writer_t *json_wtr;
          |                       ^~~~~~~~

Let's rename the variable.

v2:
- Rename the variable instead of calling the global json_wtr directly.
