fix(docker): remove deno glibc libs that break apk triggers

[raaymax]

Summary

• Replace LD_LIBRARY_PATH workaround with removing Deno's glibc-linked libs entirely
• LD_LIBRARY_PATH=/usr/lib fixed apk itself but post-install triggers (glib, shared-mime-info, gdk-pixbuf) spawn subprocesses that don't inherit it
• Now removes /usr/local/lib/lib*.so* before running apk, so all system tools use Alpine's musl libs
• Fixes CI failure on PR chore: release v3.5.0 #233 (both amd64 and arm64)

Context

Deno Alpine image ships glibc-linked libz.so.1, libcrypto.so.3, libgcc_s.so.1 in /usr/local/lib/ that shadow Alpine's musl-based system libraries. The Deno binary itself is statically linked and doesn't need them.

Upstream issue: denoland/deno_docker#373

Test plan

• Verify Docker build succeeds on both amd64 and arm64 in CI
• Verify Deno still runs correctly after lib removal
