The curl developers found test case that crashed in their testing when
using zlib patched against CVE-2022-37434, same patch we've backported
in commit 7df6795d4c ("zlib: backport fix for heap-based buffer
over-read (CVE-2022-37434)"). So we need to backport following patch in
order to fix issue introduced in that previous CVE-2022-37434 fix.

(cherry picked from commit f443e9de70)
zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow
in inflate in inflate.c via a large gzip header extra field. NOTE: only
applications that call inflateGetHeader are affected. Some common
applications bundle the affected zlib source code but may be unable to
call inflateGetHeader.

(cherry picked from commit 7df6795d4c)
Tavis has just reported, that he was recently trying to track down a
reproducible crash in a compressor. Believe it or not, it really was a
bug in zlib-1.2.11 when compressing (not decompressing!) certain inputs.
Tavis has reported it upstream, but it turns out the issue has been
public since 2018, but the patch never made it into a release. As far as
he knows, nobody ever assigned it a CVE.

This package had two patches (with two headers etc.) in one file,
which would have quilt merging them during a refresh.
Separate these patches into two files, as the original intent seems
to be having them separate.

The buildroot pkg-config (in staging_dir/host/bin) overrides the prefix
and exec_prefix variables in *.pc files, to supply the correct
(buildroot) paths for callers. If other variables are not defined
relative to prefix and exec_prefix, then the returned values will be
incorrect.
The default zlib.pc file generated by cmake contains absolute paths.
This patches the file to use relative paths (relative to ${prefix} and
${exec_prefix}).
