ceph.spec: build with system libpmem on fedora and el8

* build with WITH_SYSTEM_PMDK=ON on fedora, as f32 and f33 ship
  libpmem1.8 and libpmem1.9 respectively. and we need libpmem v1.7
* build with WITH_SYSTEM_PMDK=ON on el8, as el8 and CentOS8 AppStream
  ships libpmem v1.6,

quote from nvml.spec:

> By design, PMDK does not support any 32-bit architecture.
> Due to dependency on some inline assembly, PMDK can be compiled only
> on these architectures:
> - x86_64
> - ppc64le (experimental)
> - aarch64 (unmaintained, supporting hardware doesn't exist?)

so far, only x86_64 and ppc64le packages are built.
