runtime/mercury_float.c:
Fix a bug in MR_sprintf_float where it would convert 1.8e-10
into "1.80000000000000e-1" instead of "1.8e-10".
The problem was that it was stripping the zeros off the end of the string
produced by sprintf without considering the case where the output
was in scientific notation.
The fix is to remove the `#' from the sprintf format string and then to
append ".0" to the string if there is no "." or "e".
