chore(aur): refresh -git pkgver in update.sh and bump to 2.2.0.r1.g82e9654

makepkg --printsrcinfo does not run pkgver(), so the -git .SRCINFO kept
the version from when the package was created and push.sh never had a
change to publish. update.sh now runs makepkg -od --noprepare first so
pkgver() writes the current git describe version into the PKGBUILD.
