* fix: asar integrity test recognizes SIGABRT as a crash

5882758

ValidateIntegrityOrDie() exits via LOG(FATAL)'s call to
base::ImmediateCrash(). There's been churn there upstream between
5332940 and 5882758 on whether to use SIGTRAP or SIGABRT.  For now,
let's accept both until the churn is done.
