Title:
  CONFIG_LSM should not specify loadpin since it is not built

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Disco:
  Won't Fix

Bug description:
  [Impact]

  While inspecting our kernel configs, I noticed that "loadpin" is
  present in the CONFIG_LSM string but CONFIG_SECURITY_LOADPIN is not
  enabled. This is harmless but should be cleaned up.

  [Test Case]

  Ensure that /sys/kernel/security/lsm still contains
  "capability,yama,apparmor" after rebooting into the new kernel:

  $ cat /sys/kernel/security/lsm 
  capability,yama,apparmor

  Ensure that the current kernel's config does not specify "loadpin" in
  the CONFIG_LSM value:

  $ grep CONFIG_LSM= /boot/config-$(uname -r)
  CONFIG_LSM="yama,integrity,apparmor"

  [Regression Potential]

  Low. This just limits the CONFIG_LSM value to only contain LSMs that
  are being built.
