MDEV-31045: Fix regression building on Ubuntu 18.04

Github PR #2424 regressed Ubuntu 18.04 building
other than x86_64 machines. Architecture that are
impacted are PPC64 and ARM64.
This was because of changes in debian/rules file
which caused removing dependency to package 'libpmem-dev'
and CMake which '-DWITH_PMEM' removing not working
correctly. Package libpmem-dev was removed but
it still required to have PMEM with CMake which.
Commit make change that -DWITH_PMEM is correctly removed
if it's not wanted.
