nptl: Move pthread_attr_setaffinity_np into libc

Browse Source 
This is part of the libpthread removal project:

    <https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html>

The symbol did not previously exist in libc, so a new GLIBC_2.32
symbol is needed, to get correct dependency for binaries which
use the symbol but no longer link against libpthread.

The abilist updates were performed by:

git ls-files 'sysdeps/unix/sysv/linux/**/libc.abilist' \
  | while read x ; do
    echo "GLIBC_2.32 pthread_attr_setaffinity_np F" >> $x
done
python3 scripts/move-symbol-to-libc.py pthread_attr_setaffinity_np
