[PATCH v2 1/4] .pytool/EccCheck: Locate BaseTools dir with EDK_TOOLS_PATH

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <Pierre.Gondois@arm.com>

The BaseTools directory is currently being located as a
sub-directory of the WORKSPACE env var. This might not be
true in other environments. Cf EDKII Build Specification,
s4.1.3 "Build Process Restrictions":
  There is no restriction on the location of the EDK_TOOLS_PATH,
  it may be located within a directory identified as the
  WORKSPACE directory, or in any other location that is
  accessible on the development workstation.

Locate the BaseTools directory using EDK_TOOLS_PATH instead.
