Prevent root owning of /var/lib/libuuid/clock.txt

Just after the installation, calling uuid_generate_time() or
uuid_generate_time_safe() as root may create root owned
/var/lib/libuuid/clock.txt, which makes it unusable for uuidd.

To reproduce:
zypper rm uuidd
zypper in uuidd
uuidgen --time
ls -l /var/lib/libuuid/clock.txt
rcuuidd start
ls -l /var/lib/libuuid/clock.txt

Before:
-rw-rw---- 1 root root 56 Mar  4 17:24 /var/lib/libuuid/clock.txt

After (with the patch):
-rw-rw---- 1 uuidd uuidd 56 Mar  4 17:30 /var/lib/libuuid/clock.txt
