* 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.

+ https://chromium-review.googlesource.com/c/chromium/src/+/5894233
+
+The `CHECK_EQ()` being removed here is failing in the Chromium roll.
+I experimented with backporting the `CHECK_EQ()` to `main` and it's
+failing there as well, so some pre-existing behavior in Electron is
+incompatible with this assertion.
+
+I will file an upgrades-followup-task issue in Electron and try to
+track down the source of this problem & figure out if we can fix it
+by changing something in Electron.
