Rename suser_cred()'s PRISON_ROOT flag to SUSER_ALLOWJAIL. This is

somewhat clearer, but more importantly allows for a consistent naming
scheme for suser_cred flags.

The old name is still defined, but will be removed in a few days (unless I
hear any complaints...)

Discussed with:	rwatson, scottl
