mdocml: use less(1) as default pager.

util-linux more(1) is not an acceptable default since it cannot scroll
back in a pipe (contrary to OpenBSD more(1)).

Use less(1) instead, it's part of base-system and everyone I know uses it.

You can easily revert to a broken pager by setting "MANPAGER=more".

Closes #4375.
