test/pkcs7: Add Windows CRLF EOF to data files

Windows tests are failing pkcs7 verification due to differnt line
endings. Therefore, add make instuctions for building the data
files with Windows EOF instead. As a result, regenerate other data
files so that verification works.

Add these CRLF EOF files to the exception in check_files to ignore
the line endings.
