macos/linux: fix NetworkServiceInProcess feature name (was "2"-less variant)

The Chrome 130+ feature that runs the network service inside the browser
process is named "NetworkServiceInProcess2" (the "2" was appended when the
implementation was significantly refactored).  The tests were passing
"NetworkServiceInProcess" (no "2"), which Chrome silently ignores, so the
network service was still spawned as a utility subprocess.

On macOS CI runners the utility subprocess calls bootstrap_look_up for the
MachPortRendezvousServer and gets BOOTSTRAP_UNKNOWN_SERVICE (1102), then
terminates with "No rendezvous client, terminating process (parent died?)".
This causes the browser to report the network service crash and restart in
an infinite loop, preventing any page from loading.

Fix: use "NetworkServiceInProcess2" so the network service runs inside the
browser process and no bootstrap_look_up is needed.

Also removed --disable-features=StorageServiceOutOfProcess from both test
files: that feature name does not exist in Chrome 146 (confirmed via the
Chromium 146.0.7680.179 source tag), so the switch was silently ignored.
