Add build tag to omit grpc

This is needed so we can build the runc shim without grpc as a
transative dependency.
With this change the runc shim binary went from 14MB to 11MB.
The RSS from an idle shim went from about 17MB to 14MB (back around
where it was in in 1.7).

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
