rules: block: add support for pmem devices (#3683)
Persistent memory devices can be exposed as block devices as /dev/pmemN and /dev/pmemNs. pmemN is the raw device and is byte-addressable from within the kernel and when mmapped by applications from a DAX-mounted file system. pmemNs has the block translation table (BTT) layered on top, offering atomic sector/block access. Both pmemN and pmemNs are expected to contain file systems. blkid(8) and lsblk(8) seem to correctly report on pmemN and pmemNs. systemd v219 will populate /dev/disk/by-uuid/ when, for example, mkfs is used on pmem, but systemd v228 does not. Add pmem to the whitelist.
