[Buildroot] [git commit] openvpn: Add explicit support for external lz4

commit: https://git.buildroot.net/buildroot/commit/?id=65e6f6ff2adc21f2fea4c0c8bc4dcd9e3b865264
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

2.4.0 added lz4 support. Make that choice explicit or the bundled compat-lz4
"stub" will be used.
