example/python: avoid falling back to CLOCK_MONOTONIC

Browse source 
According to the D-Bus API specification we return CLOCK_BOOTTIME only.
We don't support kernels too old to have it -- the fall back to
CLOCK_MONOTONIC is only there to be able to run unit tests on RHEL 6
kernel and will eventually go away.
