pycompile: allow to force compilation

Browse Source 
By default, compile_dir() relies on the modification time to know if a
python file has to be built again. However in some circumstances (when
doing reproducible builds), modification times are not reliable. Thus,
this patch adds a way to force the rebuild of all python sources.
