Remove the temporary context variable `tctx` to simplify the code. use
the original context `ctx` directly in calls to `lsm_get_self_attr`,
eliminating redundancy without any functional changes.

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.

Add selftests for the three system calls supporting the LSM
infrastructure. This set of tests is limited by the differences
in access policy enforced by the existing security modules.
