mingw: Fix NO_LOCAL_CLIENT_CRED build
Commit 4b4b9086 "os: support new implicit local user access mode [CVE-2015-3164
2/3]" carefully places the relevant code it adds under !NO_LOCAL_CLIENT_CRED,
but unfortunately doesn't notice that NO_LOCAL_CLIENT_CRED is defined as a
side-effect in the middle of GetLocalClientCreds(), so many of these checks
precede its definition.
Move the check if NO_LOCAL_CLIENT_CRED should be defined to configure.ac, so it
always occurs before it's first use.
v2:
Move check to configure.ac
v3:
Use AC_CACHE_CHECK and name cache varaible appropriately
