    scripts/lsan_suppressions.txt: Add more leaks

    Running "make check" with the clang leak sanitizer reveals some
    leak reports which are either not our problem or else not
    a leak which is worth our time to fix. Add some suppressions
    for these.

    While we're touching the file, add the usual SPDX header
    and a comment explaining how to use it.
