Subject: [PATCH 06/20] kbuild: scripts/install.sh: handle compressed/uncompressed kernel images

For x86, the default kernel image is compressed, but other architectures
allowed both compressed and uncompressed kernel images to be built.  Add
a test to detect which one this is, and either name the output file
"vmlinuz" for a compressed image, or "vmlinux" for an uncompressed
image.

For x86 this change is a no-op, but other architectures depend on this.
