[yocto] [meta-selinux][sumo][PATCH 3/7] libselinux: Fix build with musl libc.

[Joe MacDonald]

From: Piotr Tworek <tworaz666 at gmail.com>

Musl libc does not implement file traversal functions from fts.h.
Oe-core provides fts library which implements those. Libselinux makefile
allows us to use such additional library by specifying required linker
flags via FTS_LDLIBS variable.
