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

Use SOX_FMT_PKG to retrieve magic dependencies (e.g. bzip2 or zlib)
indeed -lz (i.e. ZLIB_LIBS) was wrongly removed by commit
6ff0e9322f9891f5a6ac6c9b3bceffbfca16bec3. This will fix the following
static build failure:

configure:11677: checking for magic_open in -lmagic
