Revert "[man pages]: Define page-local `MR` fallback."

This reverts commit 18d708e489758636ff9e168eee2592591755eb61.

Unfortunately my clever hack [sic] does not work with mandoc 1.14.5,
causing that tool to truncate the entire text of the man page after the
summary description.

The good news is that there is a simpler replacement that works better,
forthcoming.
