[Rpm-maint] [rpm-software-management/rpm] Drop %_lto_cflags macro afterall (#813)

This was only added in commit 2bb7b0cf066c97a9d92eb0bf59618896000cb29d,
but turns out that this kind of usage is bad for build reproducability
because the system-specific CPU count gets recorded RPMTAG_OPTFLAGS
and the resulting binaries too (depending on gcc flags).
In addition, gcc upstream has decided to make -flto default to
autodetected parallelism. Since -flto can be overridden with
by simply appending -fno-lto for the packages that need to disable it,
there's no practical need for us to provide such a macro for disabling
either.
