[ptxdist] [PATCH] grpc: version bump 1.17.0 -> 1.17.2

[Clemens Gruber <clemens.gruber@pqgruber.com>]

The libcares deadlock problem was fixed upstream, the patch is no longer
necessary.

Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>
---

@Michael: Feel free to squash/fixup the 'grpc: new package' patch with
this one.
