protobuf: apply fix for pkg-config pthread flags

This upstream fix solves an issue by which the protobuf pkg-config
linker flags did not provide -pthread. This can result in segmentation
faults due to no available pthread library.

See https://github.com/protocolbuffers/protobuf/issues/8059 for details
on the issue.
