Fix the test name executable for normal dist test (#123)

The h5bench.py and documenation name and reference this test as
h5bench_write_var_normal_dist but the compiled target is missing
the "var" substring so the test is not callable from a json
config file.
Fixing the binary name aligns the test with its expected calling
convention.
