sys-apps/iproute2: Make sure that CFLAGS is in LDFLAGS

Upstream build system does not automatically add it, and GCC recommends that
CFLAGS always be in LDFLAGS.

Upstream GCC recommendation is here:
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-flto

Bug: https://bugs.gentoo.org/929233
