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.

This should go to Linus prior to the next rc.  Linus, I think this is
with picking up now as I smell a final release soon.

FWIW a git grep of "kernel/module\.c" reveals no other code users of
this path.
