Bazel client: reduce dependency on POSIX API

We can now compile blaze_util_windows.cc with
MSVC, yay! (when building //src:bazel
--cpu=x64_windows_msvc -k).

There are a lot of #ifdef's and TODOs so this
is a modest victory for now.

In this change:

- change blaze::MakeDirectories to return bool
instead of int, since that's how it was used
anyway, and to expect the permission mask as
unsigned int instead of mode_t, since the
former is good enough and compatible with
mode_t on POSIX while mode_t is not defined on
Windows

- move blaze::MakeDirectories into
blaze_util_<platform>

- implement envvar-handling in
blaze_util_<platform> and use it everywhere
