make.sh: Define a new build tag libdm_no_deferred_remove
libdm started offering deferred remove functionality from version
1.02.89. As docker still builds against older libdm, define a tag
libdm_no_deferred_remove to determine whether we are compiling
against new libdm or older one and enable/disable deferred remove
functionality accordingly.
