Refactor bootstrap error handling with helper

Extract repeated fatal-error logic into a `_bootstrap_die` helper across alpine-install.func, build.func, and install.func. The helper uses `msg_error` when available, falling back to stderr, then exits with code 115. Inline error blocks are replaced with cleaner one-liner `|| _bootstrap_die` calls.
