Increase filter time value for failing ftime-trace-granularity test (microsoft#6532)

ftime-trace-granularity test was failing in test runs due to the
configured time filter value being too small. The latest test run was
recording duration times of 322308 which is larger than the test's
specified filter value of 99999 causing timings to not be filtered out.

The test is now updated to have a filter value of 999999, which should
properly filter out timings.

Fixes microsoft#6528
