[PATCH] BaseTools:Updata the Judgment Method of "--exclude"

["Fan, ZhijuX" <zhijux.fan@intel.com>]

[-- Attachment #1: Type: text/plain, Size: 2596 bytes --]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1944

--exclude cannot be used under certain circumstances
1.The value of the parameter USES an absolute path
2.The value of Exclude parameters is based on the value 
  of the Path parameter
Neither of these approaches currently works

This patch is going to fix that issue.
