Revert "lib/pager: Apply pager-specific fixes only when needed"

Less is not always detectable, as it can be hidden behind symlinks or
wrapper as for example in a default Debian installation.
Also testing for the literal string "less" does not match full path
specifications like "/usr/bin/less".

Instead always apply the fixes.

This reverts commit c10ad975895372122f72c8d9da089b6ea69f778b.
Closes #2951
