Update settings to use latest IDs for zones

Various zones in timezones.xml were being identified by old
IDs. The settings picker and setup wizard uses the exact
ID when pre-selecting the user's current zone. Since the
autodetection uses the new IDs in places like Buenos
Aires users would not have the correct zone pre-selected
during setup.

Thanks to Marcio Ikeda of LG for the report.

Other legacy IDs found with:

for TZ in `grep 'id=' timezones.xml \
    | awk -F\" '{ print $2 }'`; do \
grep ${TZ} ~/Downloads/tzdata2016g/zone.tab > /dev/null; \
if (( $? != 0 )); then echo Bad: ${TZ}; fi; \
done

New IDs found using tzdata NEWS and "backward" file.
