The content of a .tox folder should not be considered when building
srpms. Additionally, as this folder can be fairly large and include
tens of thousands of files, a find listing can take some time. This
commit updates these find commands to exclude the .tox folder from the
search in order to save time if a user has run tox tests prior to the
build.
