[PATCH] BaseTools: suppress usage instructions with rebuild options

[Yonghong Zhu <yonghong.zhu@intel.com>]

From: Chris Ruffin <chris.ruffin@intel.com>

When using edksetup.bat Rebuild, the script outputs usage instructions
to the console, when no usage error is encountered.  Update the usage
instructions and suppress these usage instructions when using the
Rebuild, ForceRebuild options.
