eglibc: Upgrade recipes 2.16 -> 2.17

eglibc: Upgrade recipes 2.16 -> 2.17

Drop patches that are applied upstream

Fix the license checksums for changes in LICENSES file
the new changes add more copyright notices that were missing earlier

Moving ports is no longer needed since ports is now part of libc proper

Refresh tzselect-sh.patch to accomodate upstream changes

C++ headers discovery relative to target sysroot is fixed differently
upstream hence we drop use-sysroot-cxx-headers.patch

aarch64 support is already available in 2.17 hence drop the local
patches
