[ovs-dev] [PATCH v1 4/4] travis: Enable OVS Travis CI for arm

[Lance Yang]

Enable part of travis jobs with gcc compiler for arm64 architecture

1. Add arm jobs into the matrix in .travis.yml and define dpdk cache
directory for arm64 architecture.
2. Temporarily disable sparse checker because of static code checking
failure on arm64

Successful travis build jobs report:
https://travis-ci.org/yzyuestc/ovs/builds/614299933
