package/bash: add upstream patches up to patch level 23

We unfortunately cannot easily download these because of the file names (not
ending in patch) and patch format (p0), so convert to p1 format and include
in package/bash with the following script:

j=1; for i in 19 20 21 22 23; do
    file=$(printf '%04d-patch44-0%d.patch' $j $i)
    cat > $file << EOF
>From https://ftp.gnu.org/gnu/bash/bash-4.4-patches/bash44-0$i

        sed -e 's|^\*\*\* \.\./|*** |' -e 's|^--- |--- b/|' >> $file

    j=$(( j + 1 ))
done
