[Buildroot] [PATCH] package/imlib2: add zlib dependency

[yegorslists--- via buildroot <buildroot@buildroot.org>]

From: Yegor Yefremov <yegorslists@googlemail.com>

The demo programs, which have always been built and are still enabled by
default, gained a zlib dependency in imlib2 1.12.3: upstream commit
f8a451043871 ("imlib2_load: Add crc32 printout") started using zlib's
crc32() in imlib2_load, and 31006b425e11 ("imlib2_view: Optionally show
crc32 of image data") did the same for imlib2_view. Both hardcoded -lz.

Upstream commit b9555030dace ("autofoo: don't hardcode zlib flags"),
first released in 1.12.4, replaced -lz with $(ZLIB_LIBS) and added an
unconditional PKG_CHECK_MODULES(ZLIB, zlib) to the demo programs branch
of configure, turning the previously silent link-time requirement into a
configure failure:

  checking for zlib... no
  configure: error: Package requirements (zlib) were not met:

  Package 'zlib' not found

As Buildroot went straight from 1.7.3 to 1.12.5 the intermediate state
was never packaged, but the dependency has in fact been missing since the
crc32 support landed.
