www/chromium: Update to 68.0.3440.84

Changelog: https://chromium.googlesource.com/chromium/src/+log/67.0.3396.87..68.0.3440.84?pretty=fuller&n=10000

At the moment pkg-message says that in order to work around the hanging tabs problem the user may wish to run the following commands:

# [ -d ~{user}/.cache/chromium ] || mkdir ~{user}/.cache/chromium
# echo "md $(echo ~{user})/.cache/chromium mfs rw,late,-w{user}:{group},-s300m 2 0" >> /etc/fstab
# mount ~{user}/.cache/chromium

Add fix-hanging-tabs.sh script to the DATADIR [1], which simplifies the process to just running

/usr/local/share/chromium/fix-hanging-tabs.sh $user $group
