[OE-core] [thud 1/7] kernel.bbclass: fix installation of modules signing certificates

[Armin Kuster]

From: Dmitry Eremin-Solenikov <dmitry_eremin-solenikov at mentor.com>

If one has provided external key/certificate for modules signing, Kbuild
will skip creating signing_key.pem and will write only signing_key.x509
certificate. Thus we have to check for .x509 file existence rather than
.pem one.
