graphviz: Fix build to not use $prefix as search dir

The graphviz configure script used $prefix/include and $prefix/lib search
directories, thus bypassing the recipe sysroot, which could lead to build
contamination or failures. The added patch (backported from graphviz 9.0.0)
fixes this.

Due to the $prefix != /usr check in the configure script, this issue only
showed up for recipe build variants which use a different prefix value,
such as nativesdk-graphviz (prefix = SDKPATHNATIVE/...) or graphviz-native
(prefix = STAGING_DIR_NATIVE/...). Using STAGING_DIR_NATIVE is probably not
a problem, since it is recipe-specific anyways, but using SDKPATHNATIVE
may be a problem, if it happens to exist and contains headers/libraries.
Even though this may be unlikely with the default SDKPATH =
"/usr/local/oe-sdk-hardcoded-buildpath" value used in bitbake.conf,
the problem can still be triggered, especially if the paths like prefix
or SDKPATH are customized in a build.

+Subject: [PATCH] Autotools: fix: do not put '$prefix' based paths in
+ compilation flags
+
+This was causing problems with cross-compilation with a dedicated sysroot,
+because compilation would incorrectly use headers and libraries from the
+`--prefix` path. The `--prefix` path is meant to indicate a target path to
+install to, not a path from which to source dependent libraries.
