Subject: [PATCH] fix(appimage): wrong $ARCH used by linuxdeploy #36712

Problem:
In scripts/genappimage.sh running on arm64 host, the $ARCH will be set to
'arm64' before calling linuxdeploy, which cause linuxdeploy to generate
an 32bit ELF executable instead 64bit. See the issue for more details.

Solution:
Keep $ARCH unchanged, use $ARCH_OUTPUT in the output file name. On arm64
host, $ARCH_OUTPUT will be converted to 'arm64'.
