Bump & various enhancements

• We can now workaround a proot bug and pass long V8 flags to deno. So wasm-run now supports wasm tail calls.
• For convenience, wasm-run now maps the entire host system and sets PWD to its own working directory, this is required for some tests in the GHC testsuite.
• The env script now respects existing CONF_*/CONFIGURE_ARGS in the environment. It also sets CROSS_EMULATOR which is required by the testsuite.
• Add --compress-relocations --strip-debug to default linker args to output smaller wasm modules.
