libcryptoc: Cleanup build messages

This patch cleans up all of the nonformatted make output generated
from calling out to libcryptoc's make script.
This makes no functional change.

# WITHOUT this fix, we see the following when libcryptoc.a is dirty:
>   VERSION ec_version.h
> make obj=/mnt/host/source/src/platform/ec/build/hatch_fp/cryptoc SUPPORT_UNALIGNED=1 \
> 	CONFIG_UPTO_SHA512= -C /mnt/host/source/src/third_party/cryptoc
>   MKDIR   /mnt/host/source/src/platform/ec/build/hatch_fp/cryptoc
>  CC      util.c

# WITHOUT this fix, we see the following when libcryptoc.a is clean:
>   CC      RW/common/version.o
> make obj=/mnt/host/source/src/platform/ec/build/hatch_fp/cryptoc SUPPORT_UNALIGNED=1 \
> 	CONFIG_UPTO_SHA512= -C /mnt/host/source/src/third_party/cryptoc
> make[2]: '/mnt/host/source/src/platform/ec/build/hatch_fp/cryptoc/libcryptoc.a' is up to date.
>   LD      RW/ec.RW.elf

# WITH this fix, we see the following when libcryptoc.a is dirty:
>   MAKE    cryptoc/libcryptoc.a
>   MKDIR   /mnt/host/source/src/platform/ec/build/hatch_fp/cryptoc
>   CC      util.c
> ...
>   AR      libcryptoc.a

# WITH this fix, we see the following when libcryptoc.a is clean:
>   CC      RW/common/version.o
>   MAKE    cryptoc/libcryptoc.a
>   LD      RW/ec.RW.elf

This also fixes the following error:
warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.
