The oss-fuzz code uses an lsan_suppressions file to suppress certain leak-sanitizer cases that are known issues or not our code's bug. This is useful more widely than just for the fuzzer harness: if you want to build QEMU with the leak sanitizer enabled and run 'make check' then you will want to suppress some bogus leak reports.
Move the file up a directory, and add the usual SPDX identifier and a comment describing how to use it.
