scripts/gdb: Fix gdb 'lx-symbols' command

Currently the command 'lx-symbols' in gdb exits with the error`Function
"do_init_module" not defined in "kernel/module.c"`. This occurs because
the file kernel/module.c was moved to kernel/module/main.c.

Fix this breakage by changing the path to "kernel/module/main.c" in
LoadModuleBreakpoint.
