AppImage and snap builds fail on ARMv7

[6XGate]

• Version: 22.9.1
• Electron Version: 8.5.5
• Electron Type (current, beta, nightly): current
• Target: armv7l/arm/arm32

Unable to build an AppImage for --armv7l due to missing xz compressor in mksquashfs. This affects both AppImage and snap on ARM 32-bit since snap seems to rely on AppImage. This is also noted in electron-userland/electron-builder#5153
