add redis rmp builder

In the arm env, redis needs to set the --with-lg-page=16 --with-lg-hugepage=21 when to build jemalloc
For details, needs to refer to: redis/docker-library-redis#254

Note:
1. The rmp build must be executed on an arm based environment.
2. The make check in the redis source is disabled as the new parameters will fail the jemalloc test, it needs more investigation.
