[Buildroot] [PATCH 1/1] support/kconfig: fix compile warning because of missing include.

[Peter Seiderer]

With commit b58bf60b519353e983e372f5627d639e7cc72a7a the libgen.h
include was removed from confdata.c, but it is needed for the dirname
function declaration.

Fixes the following compile warning:
./confdata.c: In function ‘conf_split_config’:
./confdata.c:849:6: warning: assignment makes pointer from integer
without a cast
