zipl/boot: compile the bootloaders only if HOST_ARCH is s390x

Browse Source 
The zipl bootloaders are s390x specific, so only build them if the
`HOST_ARCH' is set to s390x.

While at it, rename `INC_FILES` to `EMBEDDED_BOOTLOADERS`. Also
introduce `EXTERNAL_BOOTLOADERS` variable and use it in the `install`
Makefile target.
