pager: move pager-specific setup into the build
Allowing PAGER_ENV to be set at build-time allows us to move
pager-specific knowledge out of our build. This allows us to
set a better default for FreeBSD more(1), which pretends not to
understand ANSI color escapes if the MORE environment variable
is left empty, but accepts the same variables as less(1)
