util: Add a file to suppress spurious lsan leaks in the python lib.
The python interpreter does some fancy things with memory which trips up
the lsan leak checker which comes along with asan. This file simply
tells lsan to ignore those leaks.
To use it when running a binary, set the LSAN_OPTIONS environment
variable to "suppressions=${PATH TO SUPPRESSIONS FILE}". To disable the
a report on the leaks that were suppressed, you should also set
"print_suppressions=0". Multiple options can be set by seperating them
with ":"s.
LSAN_OPTIONS=suppressions=util/lsan-suppressions:print_suppressions=0
