fix: Chromium not launching in ISO builds

- build-iso.sh: Create symlink chromium -> chromium-browser (Ubuntu
  installs binary as 'chromium-browser' but WhaleOS launches 'chromium')
- NativeAppsLauncher.qml: Auto-detect binary name with 'which' fallback,
  add --disable-gpu and --disable-software-rasterizer for QEMU/VirtualBox
  software rendering environments
