[Chromoting] Call SendSAS() directly from the host.

[Chromoting] Call SendSAS() directly from the host.

In order to call SendSAS() successfully the calling process's binary has to:
 - be signed.
 - be installed under %ProgramFiles% or %SystemRoot%\system32.
 - specify uiAccess='true' in the manifest.
 - run under SYSTEM or the currently logged-on user.

All of those requirements are met now, so SendSAS() can be called directly.

lgtm with optional suggestion.

File remoting/host/sas_injector_win.cc (right):

remoting/host/sas_injector_win.cc:173: // if the policy does not allow services
to generate software SAS.
Does the reference to "services" need updating?

Well, I cannot get this CL to work. The host now complies with all requirements
imposed by SendSAS() and I manually signed it. Nevertheless SendSAS() does not
work, so I'm going to abandon this CL. Thanks for reviewing it!

The problem was that ninja does not embed manifest to the binary, while msbuild
does.
