package/zbar: bump to version 57d601e82089f2f31de9e1683c3834f237421f5d

When building statically zbar, build fails on:
configure: error: unable to find libv4l.so

The following errors are raised in config.log:
configure:19371:
/home/buildroot/buildroot-test/instance-0/output/host/bin/arm-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -O2 -g2  -static -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -static conftest.c -lv4l2 -lpthread  >&5
/home/buildroot/buildroot-test/instance-0/output/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libv4l2.a(libv4l2_la-libv4l2.o): In function `v4l2_set_src_and_dest_format':
/home/buildroot/buildroot-test/instance-0/output/build/libv4l-1.16.2/lib/libv4l2/libv4l2.c:952: undefined reference to `v4lconvert_supported_dst_format'

To fix this error, bump to version
57d601e82089f2f31de9e1683c3834f237421f5d to replace AC_CHECK_LIB by
PKG_CHECK_MODULES to find the correct library (-lv4lconvert but also
-ljpeg, ...)
