gstreamer1.0-plugins-bad: Transition to meson based builds

This update follows [427eb30f9b59972b38ae3f25094470bb7034547d]
in upstream, which trasnitions the gstreamer1.0 plugins build
from autotools to meson build.

Additional patches included in meta-freescale are:
- Backport of 2 patches to allow using OpenCV version 4.1.0
- Adaptions required in NXP fork to use meson
- One patch which solves the data dir search on OpenCV.

+Subject: [PATCH 2/2] opencv: resolve missing opencv data dir in yocto build
+
+When Yocto build is performed, opencv searches for data dir using simple
+test command, and this fails because pkg-config provides an absolute
+path on the target which needs to be prepended by PKG_CONFIG_SYSROOT_DIR
+in order for the 'test' utility to pick up the absolute path.
+
+Upstream-Status: Inappropriate [OE-specific]
