bash: add upstream security fixes to patch level 12
Fixes CVE-2017-5932 - Shell code execution on tab completion of specially
crafted files. For details, see the report:
https://github.com/jheyens/bash_completion_vuln/raw/master/2017-01-17.bash_completion_report.pdf
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:
for i in 06 07 08 09 10 11 12; do
cat > bash44-0$i.patch << EOF
>From https://ftp.gnu.org/gnu/bash/bash-4.4-patches/bash44-0$i
