build: fix disk-free quota support on Solaris 10

Samba has no code to support quota on Solaris 10 (and possibly other
os's such as AIX) using the new quota interface. The new interface
serves both disk size/free space reporting (clamping the underlying
file system numbers with quota), and direct manipulation of the user's
quota.

However, there's legacy code that supports only disk size/free space on
Solaris 10. In the waf build, this code is not compiled because there is
no test for it.

This patch adds a test to see whether the legacy code can be used.

Issue reported and fix tested by Andrew Morgan <morgan@orst.edu>.
