app-arch/unzip: add 6.0_p31

Update the Debian patchset for some vulnerability fixes and use the series
file to get the right order.

I've made src_test set TZ to reduce one of the differences in the output
and also used the same dir as in src_compile, although the diff still shows
something and it doesn't seem to fail. Progress however.
