PMM-9337 Go mod tidy

* PT-1336 Added file name checks and -maxdepth 1 parameter

* PT-1336 pt-stalk removes user files from the destination directory

* Added check that files to be removed were created by pt-stalk

* Added option -maxdepth 1 to find command, so the tool does not search for files in the nested directories

* Added unit tests

* This should fix PT-1812 also
