buildhistory: Fix intermittent package file list creation

The directory that buildhistory_list_pkg_files writes to during do_package
is created by do_packagedata so a clean buildhistory doesn't have
files-in-package written during the first build since packagedata happens
after do_package.

Ensure the output package folder is created to avoid missing
files-in-package.txt files.

Also it ensures that in case of `find` fails we leave with
a hard error instead of hiding the error on the for loop.
