Fix incorrect Free Software Foundation address in the license

As detected by rpmlint,
    kexec-tools.x86_64: E: incorrect-fsf-address /usr/share/licenses/kexec-tools/COPYING
    The Free Software Foundation address in this file seems to be outdated or
    misspelled. Ask upstream to update the address, or if this is a license file,
    possibly the entire file with a new copy available from the FSF.

Replace current one with
https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt
to fix this issue.
