ceph.spec.in: %enable_devtoolset11 only if the macro is defined

there is chance that we are using `yum-builddep` to prepare the
build dependencies. in that case, gcc-toolset-11-build is not
installed. it's like a chicken-egg dilemma, but the point is
`yum-builddep` is able to pull in the gcc-toolset-11-build. once
gcc-toolset-11-build is installed, we will have the %enable_devtoolset11
rpm macro.
