Allow specifying --dirstat cut-off percentage as a floating point number.
When printing the dirstat output, floating point numbers are presented in
rounded form (as opposed to truncated). Therefore, this patch includes a
significant churn in the expected output of the dirstat selftests.
A selftest verifying floating-point percentage input has been added.

Remaining questions:
- Locale issues with strod(), e.g. decimal separator is a comma in certain
locales.
