Correct usage of sizeof() for pointer types

Given some pointer *x, calling sizeof(x) will give us
the size of the pointer (4/8 bytes) not the size fo the
underlying dereferenced structure. Use coccinelle to
search for these occurrences in the source code, and
correct them one by one. In the case of
erl_node_tables.c, the erts_snprintf() calls used a
much too small buffer.

- run_erl.c: Use the size of the signal type, not
  its pointer.
- erl_node_tables.c: Use the size of the _BUFFER in
  erts_snprintf() to make sure we can use the full space.
