[thirdparty] add jwt-cpp to thirdparty build

This is a header-only library implementing the JWT functionality.

This is the same library used by Impala for its JWT implementation, but
in Kudu we are using a snapshot which is close to 0.6.0-rc2 and contains
an extra changelist [2] to avoid patching jwt-cpp upstream source code.
