Subject: [PATCH] configure.ac: fix static linking with id3tag

Put back -lz (i.e. ZLIB_LIBS) when searching for id3tag which was
wrongly removed by commit 6ff0e9322f9891f5a6ac6c9b3bceffbfca16bec3. This
will fix the following static build failure:

configure:15290: checking for id3_file_open in -lid3tag
