[Buildroot] [git commit] libxml2: explicitly state zlib dir

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=91709de4175a27bc5cdecd4bb65b505c726e3aa1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Pass the zlib directory prefix to --with-zlib otherwise it expands into
absolute (distribution) directories leading to bad test results in
configure. Fixes:
