s3 libsmbclient: Fix fstatvfs to be more portable

The statvfs struct isn't guaranteed to be portable across operating
systems.  Since libsmbclient isn't actually calling statvfs and just
using the statvfs struct to store similar information, this patch adds
a new portable smbc_statvfs struct.  This fixes a few of the failures
in the build farm introduced by:
ae259575c447e61665c8e7070c476914161b953f

Derrell, please check.
