Subject: [PATCH] scripts/gdb: fix lx-symbols 'gdb.error' while loading modules

Commit ed66f991bb19 ("module: Refactor section attr into bin
attribute") removed the 'name' field from 'struct module_sect_attr'
triggering the following error when invoking lx-symbols:

  (gdb) lx-symbols
  loading vmlinux
  scanning for modules in linux/build
  loading @0xffffffffc014f000: linux/build/drivers/net/tun.ko
  Python Exception <class 'gdb.error'> There is no member named name.:
  Error occurred in Python: There is no member named name.

This patch fixes the issue taking the module name from the 'struct
attribute'.
