os_getenv, os_setenv: revert "widechar" impl

It's reported that the Windows widechar variants do automatically
convert from the current codepage to UTF16, which is very helpful. So
the "widechar" impls are a good direction.  But libuv v1.12 does that
for us, so the next commit will use that instead.
