Upgrade to v3.0.13

[sahal]

• Removes libvips -- didn't need it to build this version.
• Updated PKGBUILD bash variable references to always use ${} syntax.

Tested using makechrootpkg:

(ins)sahal@shakuntala[~/code/arch-pkgbuilds/joplin]$ cat mount/makepkg.sh
#!/usr/bin/env bash

export CHROOT=/mnt/large/cache/chroot
mkdir -p $CHROOT
mkarchroot $CHROOT/root base-devel

arch-nspawn $CHROOT/root pacman -Syu --noconfirm \
      electron \
      git \
      gtk3 \
      jq \
      libexif \
      libgsf \
      libjpeg-turbo \
      libwebp \
      libxss \
      node-gyp \
      nodejs \
      npm \
      nss \
      orc \
      python \
      rsync \
      yarn \
      yq \
      python-setuptools

makechrootpkg -c -r $CHROOT
