ceph.spec.in: disable lto to work around gcc-toolset-13 linker bug

gcc-toolset-13 lto can trigger a linker bug resulting in a segfault in
SafeTimer (and perhaps elsewhere).  See
https://tracker.ceph.com/issues/63867 for details.  This patch disables
lto for now now so that we can switch to gcc-toolset-13.
