On 16.04, in a fully updated LXD container:

# ldd /usr/lib/php/20151012/zip.so 
	linux-vdso.so.1 =>  (0x00007ffdbcdfb000)
	libzip.so.4 => /usr/lib/x86_64-linux-gnu/libzip.so.4 (0x00007f04346d8000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f043430f000)
	libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f04340f4000)
	/lib64/ld-linux-x86-64.so.2 (0x00005605dfc3a000)

Um, I find this incredibly confusing. You pasted a link which directly
contradicts what you state?

The list of files in xenial in libzip4 is:

File	Packages
/usr/lib/aarch64-linux-gnu/libzip.so.4	libzip4 [arm64]
/usr/lib/arm-linux-gnueabihf/libzip.so.4	libzip4 [armhf]
/usr/lib/i386-linux-gnu/libzip.so.4	libzip4 [i386]
/usr/lib/powerpc-linux-gnu/libzip.so.4	libzip4 [powerpc]
/usr/lib/powerpc64le-linux-gnu/libzip.so.4	libzip4 [ppc64el]
/usr/lib/s390x-linux-gnu/libzip.so.4	libzip4 [s390x]
/usr/lib/x86_64-linux-gnu/libzip.so.4	libzip4 [amd64]

There is no libzip5 (which would be a SOVERSION bump) in Ubuntu or
Debian (it would be called libzip5) and it would be very wrong (and bad)
for a package named libzip4 to provide a libzip.so.5 file.

Are you claiming on your 16.04 system that you have a libzip.so.5 file?
Can you run `dpkg -S /usr/lib/x86_64-linux-gnu/libzip.so.5`?
