LSM: use 32 bit compatible data types in LSM syscalls.

Change the size parameters in lsm_list_modules(), lsm_set_self_attr()
and lsm_get_self_attr() from size_t to u32. This avoids the need to
have different interfaces for 32 and 64 bit systems.

Okay, this looks better, I'm going to merge this into lsm/stable-6.9
and put it through the usual automated testing as well as a kselftest
run to make sure everything there is still okay.  Assuming all goes
well and no one raises any objections, I'll likely send this up to
Linus tomorrow.

Thanks everyone!
