Subject: Ensure symlinks to bundled gem with exts have parent dir

When configuring with `--disable-rpath` and `--static-linked-ext` (e.g.
building for WASI), `extmk.rb` doesn't build exts under bundled gems,
and `.bundle/gems/#{gemname}-#{ver}` are not created due to no call of
`extmake`.
b2491783986084770f6f97552f27b868622730cf starts creating symlink at
`.bundle/gems/#{gemname}-#{ver}/lib`, but the parent dir is not created,
so configuration aginst debug and rbs gems were failed.
