Error for not matching SPDX Tag and SPDX License File

[ant-u]

(Reference test case: test_pkg_wrong_license_file)

If package.xml has a SPDX conform tag and references an SPDX conform license file that holds the text of another license, this is only a warning. Convert this case to an error.

LicenseTagExistsCheck
 SUCCESS Found licenses ['BSD-3-Clause']
LicenseTagIsInSpdxListCheck
 SUCCESS All license tags are in SPDX list of licenses.
LicenseTextExistsCheck
 WARNING Since they are not in the SPDX list, we can not check if these tags have the correct license text:
  'BSD-3-Clause': License text file 'LICENSE' is of license Apache-2.0 but tag is BSD-3-Clause.
LicensesInCodeCheck
 SUCCESS All licenses found in the code are covered by a license declaration.
