[LTP] [PATCH] Fix static linking with musl-fts

[Fabrice Fontaine]

Don't append libraries to LDLIBS but prepend them in cpuset_lib/Makefile
and cpuset/Makefile.inc to allow the user to provide its FTS library
such as -lfts for musl/uclibc through LDLIBS

This will fix static build of ltp with musl-fts on uclibc
