Pull signature checking selftest from David Howells:
 "The signature checking code, as used by module signing, kexec, etc.,
  is non-FIPS compliant as there is no selftest.

  For a kernel to be FIPS-compliant, signature checking would have to be
  tested before being used, and the box would need to panic if it's not
  available (probably reasonable as simply disabling signature checking
  would prevent you from loading any driver modules).

  Deal with this by adding a minimal test.

  This is split into two patches: the first moves load_certificate_list()
  to the same place as the X.509 code to make it more accessible
  internally; the second adds a selftest"
