[idd] install: keep captured output in one encoding

Browse Source 
nsExec merges stdout and stderr into one pipe and detects its
encoding once. Emit UTF-16LE on both streams so error output cannot
reinterpret progress messages as CJK text.

Disable CRT buffering on both streams so progress is visible while
service and SetupAPI operations are running.
