package/libv4l: disable some options when BR2_STATIC_LIBS

Since libv4l was bumped to 1.28.1 and converted to use the meson build
system in Buildroot commit 41ce1cc690b0837a1822079317bf317ddaeac17b,
the build started failing on BR2_STATIC_LIBS=y configurations due to
compiling code that isn't compatible with static linking.

This commit fixes that by disabling the plugin code and the wrappers.
