imagemagick: bump version, fix build with zlib

The recent zlib bump broke imagemagick. This has been fixed upstream
in 6.7.5, but the xml2-config fix is still not upstream and 6.7.5
needs autoconf 2.67 to autoreconf (and we have 2.65), so we cannot
easily use that.

Instead move to the most recent version using autoconf 2.64 and
backport the fix from imagemagick svn. At the same time also
ensure zlib+bzip2 support is picked up if enabled.

-Use the detected xml2-config script
-
-The AC_CHECK_PROG() macro allows to find the location of a particular
-program. In ImageMagick, it is used to find the location of
-xml2-config, and fills it into the xml2_config
-variable. Unfortunately, the check just below hardcodes `xml2-config
---prefix`, without using the variable, which defeats the whole purpose
-of having AC_CHECK_PROG().
-
-So, let's use the ${xml2_config} variable instead. This allows to fix
-cross-compilation issues when a non-standard xml2-config location
-needs to be specified.
