take an early exit when gvprintdouble-ing a "0"

In large graphs, the value being printed is frequently zero and the snprintf in
this function shows up as a minor hotspot. Profiling with
tests/regression_tests/large/long_chain this drops the total snprintf calls
within gvprintdouble from 924019 to 858017. This lowers the contributing runtime
of gvprintdouble to overall execution from 28.89% to 28.12%.
