Move the common Pod scanning code from installman and buildtoc to pod_lib.pl

The unified code to scan lib/ for Pod is now in pods_to_install().
It returns found Pods partitioned into 'MODULE' and 'PRAGMA', as buildtoc
needs this distinction. installman installs Pods in the same order as before,
as 'PRAGMA' sort lexically after 'MODULE'.
