RR(S): JDK-7010732 SA_ALTROOT only works if running the SA tools from their build directory.

[Dmitry Samersoff]

Hi Everyone,

Please review small SA fix.

http://cr.openjdk.java.net/~dsamersoff/JDK-7010732/webrev.01/

Notice, new build system doesn't build libsaproc_audit.so so the fix
affects old-style usage only.
