[Buildroot] [git commit] package/qt5base: disable feature-relocatable

commit: https://git.buildroot.net/buildroot/commit/?id=6491ca40f8374b310a08ceb904e2a274408739af
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Disable feature-relocatable to avoid a path mismatch while searching qml
files and buildroot BR2_ROOTFS_MERGED_USR feature enabled.

As described in [1] with feature-relocatable Qt determines the search
pathes relative to the location of libQt5Core.so, with BR2_ROOTFS_MERGED_USR
enabled found first under the symlink path '/lib' instead of the install
path '/usr/lib' and searches sequentially for qml files under '/qml' instead
of the correct '/usr/qml'.
