octeon: fix imagebuilder generation by introducing generic target

The generic imagebuilder does not have a generic in the name, although
this is the default naming scheme. Use bcm53xx as template for this fix.

Before the fix:
  openwrt-imagebuilder-octeon.Linux-x86_64.tar.xz

After:
  openwrt-imagebuilder-octeon-generic.Linux-x86_64.tar.xz
