flow: Include LeakSanitizer suppression file in VPR run environment

kmurray · kmurray · commit 1c0818a29e7c · 2020-04-17T00:44:37.000-04:00
This sets the LSAN_OPTIONS='suppressions=$VTR_ROOT/vpr/lsan.supp'
environemnt variable (where $VTR_ROOT is automatically determined
by run_vtr_flow.pl).

For non-sanitizer builds this will be ignored, but passing it
ensures we don't get spurious leaks (and tests failing as a result)
when those leaks are coming from system libraries out side of VPR's
control.
