Wrong process exit code on SIGTERM

[AriPerkkio]

Describe the bug

Vite overrides exit code of the dev and preview servers when SIGTERM is captured. Exit code should be 143 but it's 0.

Reproduction

https://github.com/vitejs/vite

Steps to reproduce

Repro in Vite repository:

# Terminal 1
$ node packages/vite/dist/node/cli.js playground/alias/

# Terminal 2
$ pgrep node # Before running make there aren't other Node processes running
85978 # Pick your own ID here

$ kill 85978

# Terminal 1
# This should have exited from the node process
$ echo $?
0 # Expected 143, as other Node processes do
