libnfs: dont install libnfs-config.cmake

kodi uses its own FindNFS.cmake	to find	libnfs and succeeds with pkgconfig.
If libnfs-config.cmake is found it will also be utilized (for win/mac?)
which is generally bad for cross-compiling and causes the prefix to get hardcoded
to /usr thus libnfs.so.5.0.2 is taken from the host machine

Removing this file fixes:
| aarch64-poky-linux-ld.lld: error: /usr/lib/libnfs.so.5.0.2 is incompatible with elf64-littleaarch64
| aarch64-poky-linux-clang++: error: linker command failed with exit code 1 (use -v to see invocation)
| ninja: build stopped: subcommand failed.

Add CFLAG workaround to fix compiling with clang complaining about
old coding style while gcc doesn't care.
