fix: potential null dereference in normalizeSpawnArguments() patch (#42260)
fix: potential null deref in normalizeSpawnArguments() patch

Use upstream's practice of using `env = options.env || process.env`.
Previously, we were unconditionally assigning CRASHDUMP_SIGNAL_FD
and CRASHPAD_HANDLER_PID to options.env.

Subject: fix: enable crashpad for ELECTRON_RUN_AS_NODE linux processes
Passes the crashpad handler PID and crashdump signal file descriptor
to child processes spawned with `ELECTRON_RUN_AS_NODE` which is used
by the crashpad client to connect with the handler process.
