sci-libs/blas-lapack-aux-wrapper: Update the wrappers to avoid DT_AUXILIARY
Update the wrapper approach to avoid DT_AUXILIARY in the default case.
Now, libblas.so.3 & co. are symlinks to the FlexiBLAS library, so that
packages use it directly; libblas.so & co. are symlinks to wrappers
placed in a subdirectory, so they are only used to construct the correct
DT_NEEDED entries at build time. The advantage of this approach is that
it also works on musl, so we do not have to use two different solutions.
We are still using the full library symlink tree for the wrapper
to avoid another fight with Meson, and hopefully to reduce the risk
of compatibility issues. The library still contains DT_AUXILIARY
section, and it could still be used if one dlopens the top-level .so
file directly (rather than the .so.3).
