Update frigate-install.sh

The silent() function (used when \=silent in non-verbose mode) calls
exit on any non-zero return code. This prevents the if/else fallback
pattern from ever reaching the else branch, causing the entire install
to abort instead of gracefully falling back to CPU model.

The upstream TF/OpenVino symbol incompatibility (_ZN6tflite15metrics_wrapper...)
is not something we can fix, but the graceful fallback should work correctly.

Replaced \ with direct output suppression (&>/dev/null) so the if
condition properly evaluates the return code.
