scripts: Move lsan_suppressions.txt out of oss-fuzz subdir

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.
