examples/sotest: support packaged shared library fixtures.
Extend the examples/sotest packaging path so the shared-library test fixtures can also be prepared through nxpkg-style package artifacts. Generate shared-index.json and pkgsotest.nsh from the built modprint and sotest shared objects, recording the correct target arch/compat metadata and SHA-256 digests for the packaged shared-library fixtures. Allow sotest to run in either its existing builtin-ROMFS flow or from explicit shared-library paths, with a --mount helper mode for preparing the builtin test mount separately. Keep the paired fixture outputs in one grouped make step so parallel builds do not re-enter the generator independently. This makes the sotest shared-library example usable as a package-style fixture producer for the Dynamic ELF/nxpkg series, useful for validating the shared-library side of the packaging flow where the loader should consume installed artifacts rather than only the default builtin test paths. The existing builtin-ROMFS path is preserved with no regression to the normal sotest example flow.
