[Buildroot] [PATCH 1/7] package/cifs-utils: add optional support for keyutils

[Bernd Kuhls]

When keyutils was compiled before, cifs-utils will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/cifscreds | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libkeyutils.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
