[Buildroot] [PATCH 2/2] package/szip: remove package

[Yegor Yefremov via buildroot <buildroot@buildroot.org>]

From: Yegor Yefremov <yegorslists@googlemail.com>

szip is not maintained upstream anymore: 2.1.1 is the last release,
there is no public repository, and the source is only available from
the HDF Group archive. Its license is not a standard open source one,
and the HDF Group itself recommends libaec as a replacement.

The package also fails to build with GCC >= 15 on non-glibc
toolchains, as only linux-gnu hosts get -ansi from szip's configure
and the code relies on pre-C23 empty parameter lists:

  rice.c:1323:15: error: too many arguments to function 'winner_ref_function'; expected 0, have 2

libaec provides libsz, a drop-in replacement with the same API and
soname, so select it through the legacy option.

Fixes:
