examples: fix build with old pkg-config

Not all versions of pkg-config in distros have support for the --define-prefix flag [1], causing errors when building examples manually or with test-meson-builds.sh script [2]. For the former case, we need to remove the hard-coded use of the flag in the Makefiles. For the latter case, the flag is necessary for builds to succeed, so we skip the tests when it's not present, passing it as part of the pkg-config command if it is supported.
