  sanitizer_common: fix up onprint.cpp test

Commit D112602 ("sanitizer_common: tighten on_print hook test")
changed fopen to open in this test. fopen created the file
if if does not exist, but open does not. This was unnoticed
during local testing because lit is not hermetic and reuses
files from previous runs, but it started failing on bots.
Fix the open call.
