Fix loss of precision in pg_stat_us_to_ms()

Multiplying by the constant 0.001 can produce trailing-digit noise in
displayed values (for example 0.009000000000000001 instead of 0.009,
with default extra_float_digits) because 0.001 cannot be represented
exactly in binary floating point. Use division by 1000.0 instead,
matching code elsewhere in the tree.
