cloop: bump and fix package

On a machine without zlib-dev installed, cloop must rely on the
host-zlib compiled by Buildroot, but due to the horrible cloop build
system, this didn't happen and the build was failing.

Therefore, we now pass all the $(HOST_CONFIGURE_OPTS) when building
cloop, and we fix the Makefile so that it takes into account
CFLAGS/LDFLAGS passed in the environment or command-line and do not
override them.

[Peter: fix typos, remove HOST_MAKE_ENV]
