win32: specify _CREATE_NO_WINDOW on spawndetached()

Before this change, a console window briefly popped up on "hg serve -d" and
disappeared again, stealing the focus window (which was very annyoing when
running tests).

Specifying _CREATE_NO_WINDOW instead of _DETACHED_PROCESS fixes this (as tested
on Windows 7 x64).
