Provide time gap between uuid generation during tests

Forwarded: no
Last-Update: 2013-09-14

GNU Mach's i.e. Hurd's kernel clock is not very accurate so during
test on generating and comparing uuid's time might be same leading to
generating same Uuid. This patch adds a sleep of 1s between 2
generate statemens. Thanks to Pino Toscano.
