package/upx: new package

UPX is a free, portable, extendable, high-performance executable
packer for several executable formats.

This is needed for syslinux 6.x.

Note: upx is a host-only package. Although it supports quite a few
target architectures, the only use so far will be for use by syslinux,
which already has an x86-on-x86 requirement anyway. So we currently do
not care to have target-dependencies on host-upx.

 locate libucl; fix installation; don't add a menuconfig entry]
