Revert "[cipd] Check CIPD client hash against pinned SHA256 during updates." 

This reverts commit eebc3d82.

Reason for revert: crbug.com/874586

Original change's description:
> [cipd] Check CIPD client hash against pinned SHA256 during updates.
> 
> Linux and OSX only for now. This also rolls CIPD client to a version that
> supports pinned hashes (v2.2.5).
> 
> CIPD_CLIENT_VER and CIPD_CLIENT_SRV are no longer supported as env vars, since
> it makes no sense when pinning hashes of the binaries at specific version on
> the specific backend.
> 
> Also somewhat cleanup 'cipd' script to use "${VAR}", stderr and colored output
> consistently.
