package/kmsxx: fix meson build directory for extra tools
Commit 4e95062f8 ("package/pkg-meson: use buildroot-build for build directory")
changed the build directory for meson packages to 'buildroot-build'.
Thus accessing the build directory for installing the extra utils needs
to be adopted to this directory. Otherwise the install will fail when
BR2_PACKAGE_KMSXX_INSTALL_TESTS is enabled.
