certs: remove noisy messages while generating the signing key
When you run Kbuild with the parallel option -j, the messages from this
rule and others are interleaved, like follows:
###
CC arch/x86/mm/pat/set_memory.o
### Now generating an X.509 key pair to be used for signing modules.
###
### If this takes a long time, you might wish to run rngd in the
### background to keep the supply of entropy topped up. It
CC arch/x86/events/intel/bts.o
HDRTEST usr/include/linux/qnx4_fs.h
CC arch/x86/events/zhaoxin/core.o
### needs to be run as root, and uses a hardware random
### number generator if one is available.
AR init/built-in.a
###
On modern machines, it does not take a long time to generate the key.
Remove the ugly log messages.
