Add crgetfsuid()/crgetfsgid() helpers

Browse Source 
Solaris credentials don't have an fsuid/fsguid field but Linux
credentials do.  To handle this case the Solaris API is being
modestly extended to include the crgetfsuid()/crgetfsgid()
helper functions.

Addititionally, because the crget*() helpers are implemented
identically regardless of HAVE_CRED_STRUCT they have been
moved outside the #ifdef to common code.  This simplification
means we only have one version of the helper to keep to to date.
