[PATCH 1/2] regedit/tests: Comprehensively check for elevated privileges before starting tests

[Hugh McMaster]

Calls to regedit.exe on user accounts wit standard privileges trigger a UAC
prompt. Not responding to the prompt eventually causes a test timeout, so
use registry API calls to determine if the tests are running with elevated
privileges.
