Add NO_LOCALNAME

The pname to uid functionality at present assumes there is
an implementation of getpwnam() and that the local user
identifier is an integer.  On Windows, the local user identifier
is a SId.  Add NO_LOCALNAME as a build option so that Windows
(for now) can build without providing a getpwnam() implementation.
