Fix license tags in package.xml

[wentasah]

According to ros_license_toolkit¹ license tags should be in SPDX list of licenses. In case of claudini_ros, the license version was missing and in case of claudini_lib, the license name was not "exact". This commit changes the license tags to use SPDX license identifiers.

Note that it doesn't fix the failures reported in claudini_lib in the output below:
