Drop libdlmcontrol-dev build dependency

DLM support has been previously disabled, so libdlmcontrol-dev build dependency is not needed. Let's drop it to cut off the dependency chain.

Dropping libdlmcontrol-dev allows us to drop the following pkgs:

• libcgi-application-perl, which is failing due to nothing provides libcgi-psgi-perl
• libhtml-wikiconverter-perl
• libhtml-wikiconverter-markdown-perl
• publican
• pacemaker
• dlm
