Possibility to remove build specific information from logs

This version introduces --without_build_specific_info (-w) option that removes build specific information from logs. Example of such information could be product build identifier in DerivedData path (bolnckhlbzxpxoeyfujluasoupft in DerivedData/Product-bolnckhlbzxpxoeyfujluasoupft/Build) or hexadecimal numbers. Removing such information from logs enables to group logs by its content.
