fix: remove duplicate error handler from alpine-install.func

- Remove legacy error_handler(), on_exit(), on_interrupt(), on_terminate() and set/trap definitions from alpine-install.func (already provided by error_handler.func which is sourced on line 10)

- The local error_handler() expected positional args as required, but catch_errors() sets trap as 'error_handler' (without args), causing unbound variable error with set -u (nounset)

- error_handler.func uses default values which is set -u safe

- Also align legacy trap in install.func network_check() to standard format

Fixes #11929
