[PATCH v5 0/4] MR10748: wusa: Recognize runtime.syswow64 expressions.

[David Carrasco Flores (＠dcf1007)]

Some update manifests use $(runtime.syswow64) as an explicit target
for the 32-bit system directory. wusa currently handles runtime.system32
with WoW64-aware redirection, but does not recognize runtime.syswow64,
causing expression expansion to fail.

Map runtime.syswow64 to CSIDL_SYSTEMX86 on x86_64, matching the existing
runtime.programfilesx86 and runtime.commonfilesx86 handling.
