[PATCH 1/1] wusa: Recognize runtime.syswow64 expressions. 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.

[David Carrasco Flores]

From: David Carrasco Flores <[e-mail]>

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